• VirtualBox OSE: Install Guest OS On Headless Host Via VNC?

  - by Eddie Parker

  I've remotely installed VirtualBox OSE on my Gentoo box at home. I have everything set up and ready for the OS. However all the documentation I've read seems to say that you can only use the PUEL version in order to get remote access during installs - does anyone know if it's possible to do similar with the OSE but using VNC? Links to documentation or tutorials would be welcome, apparently my Google-Fu is failing me, if it's out there. Thanks.

• Corosync - stopping the service crashes the server

  - by Antipop

  I am trying to set up a test cluster on a Xen Server with 2 paravirtualized CentOS 5.4 machines. I am using Pacemaker+Corosync, and following the instructions found at http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf and other sites. Anyway, when I try to manually stop the corosync service, about 80% of the times the whole VM locks up with the message "Waiting for corosync services to unload" and I am forced to shut the machine down manually. For the remaining 20%, the VM keeps responding and adds dots to the above message, but it won't actually stop the service. There aren't many resources on the internet about this particular error. Any ideas about this? Thanks in advance.

• Ubuntu Server VM: copy paste?

  - by bukzor

  I've installed Ubuntu Server under Virtualbox just to get a nice little shell. I've also installed the VirtualBox "Guest Additions" and set "Shared Clipboard: Bidirectional". I still can't seem to get any copy-paste working. Am I missing something here? I've installed gpm which gives mouse support in server mode (no X), and allows copy-paste using the mouse, but still the VirtualBox integration doesn't work.

• explanation of RAM specs, and what do I need for a Gaming rig

  - by ewok

  I am looking into upgrading my custom built PC's RAM. I use the machine mostly for gaming, but I don't really know a ton about RAM, so I wanted to ask a few questions. The research I've done tells me there is a negligible increase in speed for anything above 1600 MHz. is this true or is it worth the extra money to go higher? Other than drawing more power from the PSU, is there any real difference in performance with different voltages (1.5V vs 1.65V)? most of the kits I've found in the 2x4 1600 range have a CAS latency of 9 and timing of 9-9-9-24. For a significant increase in price (usually about 1.5x), I can get either 8 or 7 and lower timing. Is it worth the cost? What I am looking for here is someone to give a good explanation of what the different specs represent, and how that relates to the performance of the machine. Specifically, I'm looking for what specs I need to focus on for a good gaming rig. I am NOT looking for a "buy this, it's the best RAM" without an explanation of why. The information will be much more valuable as it will allow me to make my own informed decision. As they say, give a man a fish, he'll eat for a day. teach a man to fish, and he'll eat for the rest of his life.

• 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.

• Unable to ssh to a Linux VM after a day

  - by jogabonito

  I have a machine running 4 VMs on it. There is one Fedora VM which is causing me some trouble. The IPs of the VMs are something like 10.100.100.* I have a Windows PC which is in the same network. It has an IP 10.100.25.77. When I reboot the Fedora VM, I am able to ping it from my Windows PC as well as use putty to ssh to it. The next day, I cant ping it or ssh from my Windows PC. However I can ping and ssh to the other VMs on the machine. If I ssh to one of the other VMs, I can ping and ssh to the Fedora VM. Next if I restart it, things get back to normal and I can access it without any issues. The IP of the VM doesn't change after rebooting and it is statically assigned I would like to know what is causing this and how to get it fixed. As a last resort, I am thinking of running a cron job to restart the VM every night, it is not a critical server, but will be generally used occasionally in the day time.

• Failing RAM, or something else?

  - by Thanatos

  I have a IBM Thinkpad T43, currently running Windows XP. Programs were crashing, XP was blue-screen-of-deathing, (more than usual) - it was basically unusable, but I couldn't get any informative error out of XP. I booted Ubuntu off a thumbdrive, which made it to the desktop, but as soon as I started to try to do anything, X segfaulted, along with several other services, followed quickly by kernel warnings and a kernel panic. I'm currently running Memtest86+ on this machine, which is spitting out numerous errors. (16k over 3 passes, and counting) The failing areas are numerous, and look something like this: 0001055da4 - XX.X MB, etc. The addresses that fail seem to cluster around 0-20 MB, 250MB, and, more rarely, 750MB, 1000MB, and 1200MB. However, a lot (but not all) of the failing addresses that I've seen end in XXXXXXX?da4 where the ? is a 1 or a 5. The machine has two sticks of RAM, one 512MB, one 1024 MB, the 512MB mapped to the lower addresses, the 1024 MB stick following. Is this indeed RAM failure, or should I consider other things before purchasing more RAM?

• Does adding 1066Mhz DDR3 SODIMM to a 1600Mhz FSB laptop make sense?

  - by Alain Pannetier

  My previous laptop had 4x4GB 1066 Mhz DDR3. My new laptop instead has only 2x4GB 1600 Mhz DDR3. Using dmidecode I gather my FSB is set to 2300Mhz. Max Speed: 3800 MHz Current Speed: 2300 MHz 2 questions: Can somebody confirm I can safely add two "old" 1066Mhz modules to my new laptop before I treat myself to faster DDR3 modules? I understand this should not slow down the faster 2 1600 Mhz DDR3 modules. Correct? If this is of any relevance, I'm running Linux Mint Maya.

• Lenovo ThinkServer TS130 1105 - does 32/64 depend on RAM?

  - by Ecnerwal

  Just got in a Lenovo ThinkServer TS130 1105 (Xeon E3-1225V1) and a (new, sealed, holographed, looks legit) copy of Windows Server 2008 32/64 (standard) to run on it for a pretty lightweight job (currently handled, adequately, by a terrifyingly old Optima P4 running Windows 2000 server - really lightweight, but long-past-due for replacement, without any particular need or excuse for server 2012...) The 64 bit disc sits there and does nothing. The 32 bit disc boots. I haven't spotted any mention of this in the TS130 Manual (I have now combed it, and find no mention of a need to populate in pairs - a preferred order to populate in, yes, but no mention of pairs being required) but I begin to wonder if it's due to the fact that the 4GB RAM suppled with it was a single DIMM, rather than a pair. Better for upgrading, but perhaps requiring an upgrade (or sidegrade) right away to install the x64 version?? Anyone know? I tried the 64-bit DVD on a desktop with an AMD Athlon II X4 635 processor which normally runs Windows7 in 64 bit, and it booted up just fine.

• What does motherboard RAM slot colors mean?

  - by totymedli

  I always saw that the motherboard RAM slots are colored in pairs, but never know what does it means. I just put the 2 RAM in, and after a few tries it always worked. But after I tried to install a third one it always throws me a blue screen of death. Is there an order how should I install RAM to the borad? What does the colors mean? Does they indicate performance boost opportunity or are they just a guide for installation?

• Processor upgrade on a laptop vs. Ram upgrade. Also does ram always matter?

  - by Evan

  I have a Dell Inspiron 14r (N4110) with an Intel Core i3 and 4gb of ram. It runs very smoothly, however gaming on this laptop is very limited. This is mostly because of integrated graphics but i have seen a computer with a Core i5, and very similar specs otherwise, run games that the N4110 cannot. This other computer has integrated graphics and 6gb of ram. I am wondering whether upgrading ram or upgrading the processor make the most difference in performance. Which setup would get better performance, an i5 with 4gb of ram or an i3 with 8 gb of ram? (Both with integrated graphics) Also, is there a certain point at which you have too much ram for the computer to ever possibly use? For instance is there really any difference in performance between 8 gb and 16 gb of ram?

• Is there way to enable 4 GB RAM in 32-bit Windows OS?

  - by Wahid Bitar

  I upgraded my PC to 4 GB RAM and I get only 3 GB. Windows 7 32-Bit consider that I've 4 GB RAM but didn't use more than 3 GB. Someone told me that MS Windows 32-bit doesn't support RAM larger than 3 GB. So please is there any way to make my OS "Windows 7 32-Bit" support more than 3 GB RAM ? *`Note: I can't move to 64-bit because I've many program doesn't work with a 64-bit OS. Edit:: I tried what Mr. Wonsungi advised me but whenever I check this option: Enable support for 4 GB of RAM I get the following error: 'Cannot access to the registry key HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-11d1-A9F0-00AA0060FA31}.' There is no "CLSID" in my registry, I don't know why!.

• How cpu writes data to dynamic RAM

  - by Krit

  Hello, I would like to know what kind of electrical signals does a cpu send to a dynamic RAM when it wants to write one bit (a 1 or 0). Is it simply that cpu sends just a single electric pulse, and if that electric pulse's voltage is higher than a certain level, it charges the capacitor to a voltage level that is "1" and if it is at a lower voltage band, it charges capacitor to level that it is "0"?

• VM using a secondary graphic card

  - by Arthur

  Hi everyone, at the moment i have a dual monitor setup on my main PCIe gfx card. I know that on windows it is almost impossible to have a second card (eg no thrills PCI card) running without having an SLI motherboard because of a driver issue. Well this was my conclusion after many weeks of research. I was thinking...is it possible to use a VM in order to utilize the secondary card as the default video output to feed another monitor? let me know if you want me to clarify Thanks :)

• I cannot connect to home server after a few hours

  - by Iago

  I have an old PC and I decided to revive it. A LAMP (for my own use) and a P2P server (torrent and e2dk). My old PC is an AMD Athlon XP (1400 MHz) with 384 Mb of RAM First of all I installed Ubuntu Server 11.10, SSH, FTP, SAMBA and LAMP. With this configuration my home server works well, with no problem. Then I went to the P2P server and I tried rTorrent and then uTorrent Server Alpha. And here is my problem. After a few hours (maybe 10 hours, or maybe 30 hours) with the torrent app running (rTorrent or uTorrent) I lose the connection to my home server. That is, I cannot access via ssh, I cannot access the apache server, etc. but I can ping the home server. It seems that the server freezes and all I can do is reboot the server physically. So, I have two questions: What is the problem? and How can I solve it?

• How would I measure the amount of RAM needed per Glassfish domain? [closed]

  - by oligofren

  Possible Duplicate: Can you help me with my capacity planning? In our test environment we have a lot of apps spread out over a few servers and Glassfish domains. To make versioning easier I would have liked to have one Glassfish domain per customer per app (kind of like a heavyweight version of lots of jetty instances). But I have heard that Glassfish is kind of heavy on the resources, and so I would need to measure approximately how many instances would fit in the available RAM. These are low-traffic/low load testing servers, so CPU is not really an issue, though RAM might be. How would I get an approximate measure of how much RAM is needed? This is one Glassfish 3 instance with one heavy EAR application deployed. top? jvmstats? ??

• 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.

• Using Hamachi VPN to connect to Linux VM at home

  - by Cameron Verotti

  I have a CentOS 5.10 Linux box at home running on VMWare, with Windows 2008 as the host. I have set up a Hamachi VPN so that I can connect to the Host server from work, I attempted to add a second VNIC to the VM and bridged it to the hamachi Network Interface. I spun up the VM and checked eth1 with ifconfig and its throwing me a ipv6 address not a ipv4. I want to hook this VM up so that I can run a ssh command from work to the VM. MY network at home is all on Local 198.168.. hence the need to make a VPN network like Hamachi. I cannot seem to find anything that tells me or helps me with tunneling my Linux VM via Hamachi. Any help would be fantastic!

• Why can't a PC with 2 network cards be accessed by hostname?

  - by lewis

  I set up PC with 2 network cards, connected to the same LAN. I can connect to this PC (e.g. by remote desktop) only via ip-addresses. Accessing by hostname does not work. Why is this the case? UPDATE: Full environment 1. PC with 2 hardware network adapters. 2. On this PC installed VMWare Workstation. Created 3 VM's, networked by "bridged" network setting in VMWare. 3. In LAN all ip-addresses given from DHCP. 4. Win2k8 on all hosts (both physical and vitrual). As result: 1. PC has 2 ip-address (e.g. 192.168.1.71 and 192.168.1.72). PC available in LAN by ip-addreses, but not avail by hostname. 2. VM's has own ip-addr on each (e.g. 192.168.1.73, *74, *75 etc). They are available from LAN by their ip's, BUT not by their hostnames. How can I access to PC and to VM's by hostname?
