• Windows Server 2003 guest on Xen frequently stops responding

  - by smokris

  I'm running a Windows Server 2003 guest instance in Xen 3.x. This DomU runs fine for a day or two, then stops responding — I don't get any network response, and I can no longer connect to Xen's VNC console for this DomU. xm list shows this: Name ID Mem VCPUs State Time(s) Domain-0 0 6508 8 r----- 1161159.4 [A working Linux DomU] 1 512 1 -b---- 68711.1 [The hung Windows DomU] 5 512 1 ------ 67234.2 [Another working Linux DomU] 3 512 1 -b---- 163036.4 (What does the ------ mean? The xm manual explains what each of the six states mean, but not what no-state means.) If I xm destroy and then xm create the Windows DomU again, it boots right back up (with the Windows alert The previous system shutdown at [...] was unexpected.), and then stops responding after another day or two. I checked /var/log/xen/*.log, but no log messages are generated at the time the server stops responding. How should I proceed in troubleshooting this?

• Setting up web development envirnoment with a VM (ssh + browser testing)

  - by Brandon

  I am running VMware Fusion on my Mac (10.6) with an Ubuntu 9.10 (32 bit) VM for my development environment. How would I setup SSH to be able to SSH into the Ubuntu VM from the Mac? Also, when I am testing websites in browsers, how would I set it up so that I can go to the site on FF on the Mac and have it point to the site running on the Apache server on Ubuntu?

• KVM Hosting: How to efficiently replicate guests

  - by javano

  I have three KVM servers each with 1 guest VM, running directly on it's local storage, (so they are essentially getting a dedicated box worth of computing power each). In the event of a host failure I would like the guests replicated to at least one of the other hosts so I can spin it up there, until the failing host is fixed. I am curious about KVM cloning. I can clone a VM live or when it's suspended/shutdown. Obivously suspended VMs will naturally be quicker to clone but these three VMs comprise three parts of a single solution, so I don't want to ever have any one of them shutdown. How can I efficiently clone these VMs between servers? I have had a couple of ideas, but are these insane or, is there a better method I have missed for my scenario? Set up a DRDB partition between box 1 and 2 where VM 1 runs from, and so is replicated between box1 and box 2, repeat between box 2 & 3, and box 3 & 1 (This could be insane, I have never used DRDB only read about it) Just use standard KVM CLI clone options to perform live clones (I'm dubious about this because I don't know how long it will take and what the performance impact will be during) Run a copy of each VM on at least one other host, and have the guest on one host export it's data to the matching guest on another host where it can import that data, scripting this on the guest) Some of other way? Ideas welcome! Side Note These servers have 4x15k SAS drives in a RAID 10 so they aren't rocketing fast, and as I mentioned, each VM runs from the host's local storage, no NAS or SAN etc. So that is why I am asking this question about guest replication. Also, this isn't about disaster recovery. Guests will be exporting their data to a NAS over a VPN, so I am looking at how I can have them quickly spun up in a host failure situation.

• Stop OS X from switching spaces with mouse

  - by mankoff

  OS X Spaces change when the mouse hovers near the edge of the screen. Does anyone know of an app or 'defaults' command to disable this? Warp looks like it might help, but hasn't changed the behavior for me, even though I tried turning it off, or setting a modifier key.

• Identify an instance of Google Chrome by PID

  - by Laramie

  While working I generally need around 40 windows open at a time and run 100-200 processes. When memory constraints become an issue, I start picking off the processes that are the most resource intensive and disposable. Often these are chrome.exe. It would be helpful to be able to match a particularly memory-hungry instance of chrome to it's PID so I can selectively close it. That is, if I knew what the page title it is currently open to, I could choose whether it lives or dies. I've tried Process Explorer to no avail. Any ideas?

• How to tell Linux to explicitly swap out main memory of a suspended process?

  - by Vi

  I run a memory-hungry process (mkcromfs) which consumes more memory than I have physical memory on my latop, so it is paging and swappin and thrashing all the time and loadavg is about 2 (compcache is already in use with usual swap partition as well), but slowly moving forward (Although I afraid it will finally try to allocate 2GB and crash draining 2 days of thrashing). When I want to use the laptop for something else, I stop the process, start X server, firefox and other programs. The problem is that when I start Firefox the loadavg jumps to 10 and the system becomes almost unresponsive at all (long time to turn on/off caps lock, slow mouse cursor position updates, slow switching from X server to Linux console, slow login). The stopped mkcromfs still holds a lot of memory (464.8 MiB and slowly falling) and moves it to swap only when more memory is needed for some other program, which results in a great slowdown. How to tell the Linux to swap out this process entirely (e.g. I'm not intending to resume it in short term), possibly waking from swap other data? Also it will be useful to be able to specify the exact swap device to swap the given process out.

• Mac OS X - Time Machine backup fails verification - What can I do to save the history?

  - by usermac75

  Hi, How do I make Time Machine to make a new complete backup without losing older versions of backed up files? Verbose: I am using the Time Machine backup on my OS X (Snow Leopard) to backup the whole computer to an external drive. I especially like the "history", i.e. the feature that allows you to restore the older version of a file. Problem: I had some data corruption on my external backup drive, I repaired it with the System Tool for doing that, it found some faults. I had the disk tool repair the external drive. After that, the external drive was OK and I could use Time Machine again. I let Time Machine do one more backup. Now I made a verification according to http://superuser.com/questions/47628/verifying-time-machine-backups, namely along sudo diff -qr . $HOME/Desktop 2>&1 | tee $HOME/timemachine-diff.log However: After doing the command above, several differences and missing files were reported, approx. 200 files in sum. Whereas some of the missing files were cache or excluded directories, the differences do bother me, especially as some important documents from me are listed as differing. How can I make sure that the data on the external drive is synced correctly? Is it possible to have Time Machine to do a complete new backup without losing the history? Or to have Time Machine compare all files for differences and re-write all files that are different? Or can I set some flags on the files that do not match to have them copied again? (like the archive-flag in Windows/Dos). I'd rather not touch the files because I would like to keep the date of last change/date of creation) Thank you for your thoughts!

• How to install Gitlab in a VM on a production server?

  - by Michaël Perrin

  I have a production server running Ubuntu 12.04 and I would like to install on it a VM with Gitlab (using Vagrant and Virtualbox). Let's say that the address to access Gitlab is gitlab.mydomain.com . The DNS zone has been configured to point to the IP address of the server. I want users to be able to access to Gitlab (either for pushing to a repository, or for accessing to the web interface) from the outside. The VM has been configured to have an IP address. It means that when browsing http://gitlab.mydomain.com for instance, the request has to be forwarded to the VM on the server, ie. to the VM IP address. What are the ways to configure this? Can Apache be used as a proxy? In this case, I guess it only works for HTTP requests, but not for pushing to a Git repository on the VM.

• Accessing VMware Player across the network

  - by Tiffany Walker

  My network: 192.168.2.2 (computer) 255.255.255.0 (mask) 192.168.2.254 (gateway) The VMplayer is: 192.168.233.129 (ip) 255.255.255.0 (mask) 192.168.233.255(bcast) It's obvious the player can't be access from other systems because of the wrong network settings. However, I am not sure as to how to change that. Obviously I have to edit the ifcg-eth0 but I know I also need to edit it on the host system to make it accessably. Is this done from inside VMware Player? Or do I need to edit the network devices? The host box is Windows. Inside VMware is Linux.

• How can I know if a VM is used or not?

  - by Saariko

  I am running eSXI 4.1. In my main datastore I have plenty of folders, some of them has logical names, while the others don't, they hold BASE configurations/images of clients that I duplicate and activate. I only have a fraction of the actual clients loaded and running on the server. How can I know, but looking in the datastore folder, if the VM is in the inventory or not? If I right click on the vmx file, I can add it to the inventory - EVEN if the same client/folder is already active.

• Recommendations for a cloud/hosted server environment that can run different Windows VMs?

  - by Rory

  I currently have a colocated Win 2008 server that I use for hosting different windows VMs for testing: Win 2008, Win XP, Vista, Win7, Win 2000. I'd like to ditch the server and use something like Amazone AWS but the key thing is I need to be able to launch VMs for these different windows versions. AWS doesn't allow this currently. Can anyone recommend somewhere that I could use? The main reasons I want to get away from my own server are: administration: backup, windows updates, etc space: disk limitations mean I can't have all the VMs I want. I'd like to be able to pay for space incrementally. I'll typically only run 1-3 at a time but want lots of snapshots of different machines.

• What is Paging in memory management?

  - by Fasih Khatib

  I was just reading Operating System Principles by Silberschatz et al when I came across paging in memory management.I'm slightly confused about it. It states that Physical Memory(I assume it's RAM) is divided into frames, and logical memory is divided into pages. CPU generates logical addresses containing page number and an offset. This page number is used to retrieve the frame number from a page table which gives the base address so the physical address is calculated as base+offset. My question is: is the page table maintained for every process? I logically think that the answer would be yes as every process will need to map its own pages to frames. I may be wrong. Please clarify. Also: paging and segmentation(where 'holes' are created in memory) are two totally different techniques that are not used in combination. Correct?

• What is the best way to setup a heartbeat agent for failover between two VMs?

  - by EGr

  I have two VMs in VirtualBox that use NAT for their network adapters. They are both getting the same IP address, so I will need to reconfigure that; but knowing that, is it possible to set up a heartbeat agent to failover an apache server if one of the two VMs go down? The way I pictured it would be that the webserver would be able to be accessed externally via :80. No matter what VM was running, I would be able to access the website at that IP/port since failover would be setup. I'm running into trouble setting up IPs when the network adapters are set to NAT, and people have told me that I shouldn't be setting the IPs in this configuration. So what should I do to achieve what I'm looking for? Is it even feasible?

• Why do I get swap space related errors when I still have lots of free memory in Solaris 10?

  - by Tom Duckering

  I am seeing a few of my services suffering/crashing with errors along the lines of "Error allocating memory" or "Can't create new process" etc. I'm slightly confused by this since logs show that at the time the system has lots of free memory (around 26GB in one case) of memory available and is not particularly stressed in any other way. After noting a JVM crash with similar error with the added query of "Out of swap space?" it made me dig a little deeper. It turns out that someone has configured our zone with a 2GB swap file. Our zone doesn't have capped memory and currently has access to as much of the 128GB of the RAM as it need. Our SAs are planning to cap this at 32GB when they get the chance. My current thinking is that whilst there is memory aplenty for the OS to allocate, the swap space seems grossly undersized (based on other answers here). It seems as though Solaris is wanting to make sure there's enough swap space in case things have to swap out (i.e. it's reserving the swap space). Is this thinking right or is there some other reason that I get memory allocation errors with this large amount of memory free and seemingly undersized swap space?

• Virtualbox VM (spawned by Vagrant) running but inaccessible. What now?

  - by Matt V.

  I have a Virtualbox VM running Ubuntu that was started by Vagrant. At some point my ssh session connected to the guest stopped responding. I tried "vagrant halt" from a terminal window on the host (OS X). The shutdown process seemed to also hang. Shutting down the Oracle VM VirtualBox Manager doesn't shut down the VMs themselves. Is there a way in either Vagrant or VirtualBox to force the running VM to shutdown? When running desktop guest OSes, closing the GUI window presents several options for shutting down the guest, but I don't know how to do the equivalent when the guest is running headless.

• Does Win7 VPC negate need to re-install?

  - by justSteve

  I fear i have an impending hardware breakdown coming ... the last time the box booted i had to power off and on a couple times before windows loaded. Seems fine when up and running. So i'm preparing to install new hardware and would like to bring over the currently installed image. From what i've read of VM capabilities of VM i shouldn't have to re-install? VM seems most applicable to data centers and enterprises. I'd like to see some coverage of the tricks for SOHO users.

• Terminal Server CPU usage at 100%

  - by Light1c3

  I'm running a terminal server with around 50-60 users,and every so often the server will go from 40% usage to 100%. I took a closer look an it seems every time this happens, a different user or two seem to be caught in a loop and end up using < 30% where the rest of the users only use a maximum of 5%. The company behind the software we use clame it's due to the servers inadequate hardware (It's a VM system running on a dual - quad core setup) which to me sounds like BS! I'm fairly new to this level of IT so if I misspoke I apologize. I have no way to prove it but I believe adding more raw hardware power wont do me any good as this to me seems like a bug in their software, and it will suck up as much ( or little) CPU as it's given. The VM in question has 4 vCPU cores and 12 GB RAM available, and is running Windows Server 2008, 64-bit Thanks in advance for your help! Note: I have the same question posted on SO, but was pointed in this direction so just in case, here is a link to the post http://stackoverflow.com/questions/17276602/termserver-cpu-at-100

• Where to look for regular scripts?

  - by fontan

  It seems to me that our server freezes every 30 days around noon due to the huge utilization of xvda data transfer partition - writes are 50 times higher than normally (according to the health monitor in plesk). This seems to me as the reason why the apache & co becomes instable as (for example) all apache's processes are waiting to write their log (according to the service's full status). I am, however, unable to find any scheduled task that would be executed during that period. I have checked both cron and anacron setup and there is only one monthly anacron task which is not executed (according to the /var/log/cron - and there is nothing unusual) around noon. Are there any other places where to look for periodical processes? (I am just about to ask server's provider the same question about any external maintenance run around this time but I don't expect them to run anything time/resource consuming during the day.)

• Valid path to deploy vm on host

  - by ELSheepO

  I've recently added a VM to the library in SCVMM to use with MS Test Pro 2010, and run into a problem. I cannot import it using test pro, it just won't give me any option to import in the lab manager. Also, if I try to deploy it back to the host it came from, it gives me a error saying the path is not valid. Anyone have any insight into this? Also, SCVMM seems to freeze everytime I try to create a new VM from the template of the VM I've stored in the library, the same one thats giving me the problem when I try to deploy it on to the host. Thanks.

• VMWare Workstation 8 reporting ""vmx86 driver version invalid handle" problem on booting VM

  - by dommer

  I'm just doing a VMWare Workstation 8 installation. However, on trying to boot (or create) a VM, it's reporting "Could not get vmx86 driver version: The handle is invalid." It recommends reinstalling, which I've done. Also, VMWare Player just hangs. Was going to post on the VMWare forums, but can't seem to create a new discussion (even though I've registered/logged in). It's our own fault for being too eager to upgrade, I guess.

• Apache shuts down from time to time

  - by Dugi

  I'm having trouble with my VPS as it keeps shutting apache down at least twice a day. The server is running on CentOS 6 with the latest apache. By shutting down I mean I have to go into SSH and type in this command in order to bring it up again: /sbin/service httpd start I'm not very good with servers and my host doesn't seem to have a nice customer service. Any help would be appreciated as these unexpected downtimes really know to kill one's mood.

• Why is my browser using so much memory?

  - by Steve

  Hi. I've recently had problems with Firefox running very slowly when I have many tabs open; say 20 tabs. My whole system would slow down. I decided to give Google Chrome a try, and it started out fine. But lately I am finding that it too, slows down my whole system. Looking at Task Manager, chrome.exe is using about 250MB of memory in about 6 different entries in task manager. However, when I shut Chrome down, memory usage is reduced by about 600MB. How can this be? (shows drop in memory usage after ending Chrome.) When my system locks up with Chrome having many tabs open, it takes 10 seconds to load the Start Menu, 10 seconds to expand All Programs, and each folder and subfolder, and 30 seconds for the program to be highlighted under my mouse. It also takes 10 seconds to switch to Notepad. Why is Chrome appearing to use so much more memory than Task Manager indicates? Why is my pagefile being used when I have around 1.1GB of memory? Can I set Chrome to run in RAM and not in the pagefile? How can 20 tabs use 600MB? That's 30MB per tab. Thanks for your help.
