• Mac OS X Server 10.6.6 "disables" CPU in VMware Fusion

  - by wjlafrance

  I installed Mac OS X Server 10.6.0 in VMWare Fusion the other night and it worked perfectly, until I ran Software Update. I upgraded to 10.6.6 through the combo updater, and now when I start the VM it says: "The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point." I've switched the operating system in the options to OS X Server 32bit, 64bit, and even to Windows 7, and nothing has worked. Does anyone have any ideas?

• How do I now access my site for an installation

  - by user4524

  I have just rented a virtual private server with DirectAdmin. I have an ip address, lets say its: 178.239.60.18 Now I have made a new domain on the server. It resides in a folder called: example. Now when I would like to acces this in a browser, I type in 178.239.60.18/example or 178.239.60.18:example But this does not work. What am I doing wrong? When I look at the DNS record it does say the the ip address for example is 178.239.60.18

• Pages partially load on rapid refresh

  - by user101570

  I recently set up a VPS slice with 256MB to run a LAMP stack (Ubuntu 11.04, Apache2, Mysql, PHP5). So far I'm only running a simple Wordpress site on an IP-based virtual host I set up. The performance is excellent, but I've noticed that if I send multiple HTTP requests from the same IP in a short time period, only partial pages are rendered. Then if I wait a bit and refresh the page, the entire page loads again. I noticed this behaviour when accessing the site from two browsers from my office desktop, but it also presents itself if I quickly navigate the site from a single browser (any browser). I'm guessing this is an Apache phenomenon, as the pages are rendered correctly except under the conditions above, but perhaps I'm wrong here. Could it be my hosting company with some kind of DOS protection in place? As a relative Linux/server noob, I'd really appreciate any insight into what settings in Apache could explain this behaviour, and how I might go about changing it.

• How (much) is virtualization used today?

  - by BLAKE

  I know that where I have worked, I have pushed alot for virtualizing our servers. I think that it is much easier to implement and maintain than physical servers. I have been using Microsoft's Virtual Server 2005 R2 since it was released. Right now at my workplace we have 12 VMHosts that hold about 55 VMs. We have 6 other servers that we have been unable to convert to VMs. I want to know how other people in our field view virtualization. I know that I have had developers dislike the notion of VMs claiming major performance hits. What do other Sys Admins think about virtualized servers?

  - by Nrew

  I'm trying it on virtual box and installed Acronis 2010. The backup was successful but when I checked on the backup which is on my flash drive. Here's my problem: Ive installed firefox before the backup, but the program files folder in the flash drive has no folder called firefox. How do I restore the the 2 partitions using the backup. What I did was to: Go to tools & utilities in Acronis then chose clone disk. Selected the source and destination(flash drive). Then I restart, the backup began. First with the first partition which has xp installed and the 2nd was vista lite. What do I do to restore it: I only got these folders on the root of the flash drive: Documents and settings Program files Windows BOOTSECT.BAK

• VMWare Player Run as Service

  - by Marshal

  I have a VMWare Player running a VM at all times. However I want the server to run that Virtual Machine on boot (without logging in). This will allow me basically to restart the Server and when it loads to the login screen it's already running VMWare. Any ideas? I have tried reading up on it however websites suggest VMWare Server. This is no longer backed by VMWare anymore. So I am looking to either make VMWare Player a service or if anyone else has any other ideas? Running Win 7 on my server btw Thanks for looking.

• Nginx proxy SOAP request

  - by user2606078

  looking for a right way to accomplish the following: there is an app that have URL(1) hardcoded and no way/time to change it in the source http://dev.server.com/example.com/admin/soap/action/index?pr=1 and it should use (and get response from) URL(2) http://example.com/admin/soap/action/index?pr=1 what should I configure in Nginx (apache as backup used) conf on dev.server.com in order to give that app when it asks URL(1) answer from URL(2)? On dev.server.com Apache has virtual host: dev.server.com enabled. Also I've tried to proxy in apache instead of nginx by using ProxyPass: <Directory /var/www/dev> Options Indexes FollowSymLinks MultiViews AllowOverride all Order allow,deny allow from all </Directory> <Location /example.com/admin/soap> ProxyPass http://example.com/admin/soap </Location>

• Is there a "restore point" in Linux (Debian/Ubuntu) like Windows?

  - by Somebody still uses you MS-DOS

  I'm working directly in an Ubuntu Virtual Machine (VM). Some updates (like kernel) were available at the update manager. If I weren't using a VM, I wouldn't update it since it's a risk to break something. Since it's a VM, you can create a Snapshot or export an appliance and restore if something goes wrong. Suppose I'm not using a VM with a Debian/Ubuntu installation. Is there a install-restore approach that doesn't depend in a VM configuration to restore your system exactly before an upgrade (Like a "Restore Point" in Windows), being easy to restore like a VM appliance? (I'm not looking for "ghost images" or something like that (Norton Ghost, Clonezilla, etc), I'm looking for something builtin in the Linux System)

• Hyper V cluster - one VM won't migrate

  - by Chris W

  We have a Failover Cluster built up on 6 blades, each running Hyper V. Each box is running Server 2008 R2. We've got a number of VMs running that all have the same basic config: VHD stored on a cluster shared volume. 2 virtual NICs (1 for LAN connection and 1 for SAN connection). All of our VMs will happily migrate between any other blade apart from one single VM which is running fine on it's current blade but will not migrate to any other location. What could be the cause of it or where should I look to get a detailed error message as I can't seem to find much information logged in any of the logs. Edit: I know the usual culprit is mis-matching resource names. We've already been there with the NICs named differently on some of the blades. As far as we can tell now everything looks to be identical on each bit of metal.

• Installing then Running VMware or VirtualBox causes my Windows 7 PC to not boot up after shutting down?

  - by Rick

  At my work I am provided with a Windows 7 PC but I am a programmer and Windows gives me problems for doing some types of development so I want to have a virtual Ubuntu Linux machine that I can use for some things. However, I have tried with both VirtualBox and VMware and I am able to install the latest Ubuntu and run it but then when I try to restart / start the computer after it was shut down, I am unable to boot into Windows normally and end up having to go into Safe mode and then use the system restore to get my system back up and working. I am puzzled by this and would appreciate if anyone has any idea why it would be doing this, I have searched on this but can't find anything. Thanks for any advice

• Use HAProxy or Nginx to Load Balance between VPS

  - by xperator

  I want to load balance + failover backup multiple vps webservers hosted on different providers. I heard that for HAProxy you need multiple server under the same subnet, plus a shared (virtual) ip address between load balancers. But it's not possible in my case cause every VPS is on different node/network. Is there a way to use HAProxy in this kind of setup ? ( Please explain how briefly, I don't want to hear your "YES" answer ) What about NginX? Is it possible to achieve same result with Nginx ? (when servers are located on different nets) I know about Round Rubin DNS, but it doesn't provide a real failover solution, neither a load balance between servers.

• Cannot access to any windows share including localhost

  - by user21936

  I can't access any share from my operating system, including \\localhost and \\127.0.0.1. I have Windows 7. NetBIOS over IP is enabled, other computers in the network can access my shares and other computer's shares, but my operating system cannot access any share. I have installed Windows XP within VMware, and the virtual windows xp can access all shares including the host shares. I can communicate in other ways like TCP, HTTP and gaming, but not access shares. How to solve this problem?

• Why no Win16 support in 64-bit Windows?

  - by dsimcha

  My understanding (from Wikipedia) is that the x64 instruction set supports executing 16-bit protected mode code from long mode, but cannot execute real mode code without being switched out of long mode because long mode lacks virtual 8086 mode. Therefore, it stands to reason that real mode DOS apps can't be run in Win64 w/o software emulation or dynamic translation. However, why was support for Win16 protected-mode apps excluded when support for them seems (at least at first glance) to be reasonably implementable and is included in newer versions of Win32? Was it just a matter of demand not being high enough to justify implementation costs (and the win32 version was already implemented), or is there a good technical reason?

• xl create doesn't bring up console

  - by ineff

  I've tryed to run VM in Xen 4.2 using xl command (for what I get this should be standard toolstack, while xm is deprecated). In this case I've the following configuration file kernel = '/media/home_separata/domU_kernel/boot/vmlinuz-linux' ramdisk = '/media/home_separata/domU_kernel/boot/initramfs-linux.img' name = "domU_Arch_linux" memory = "512" root = '/dev/xvda1 ro' disk = ['file:/media/home_separata/domU_kernel/arch_linux_kernel.img,xvda1,w'] vif = ['mac=aa:::10:11:f1,ip=192.168.0.2,bridge=xenbr0'] when I try to start the virtual machine with xl create it seems it works (it also bring up the vif interfaces) but if I try to connect via xl console it gives an error: xenconsole: Could not read tty from store: No such file or directory the fun fact is that the I've the problem inverse using xend/xm (in that case xend doesn't bring up vif interfaces but activate console). Does anyone have any suggestion?

• Virtualbox, merging snapshots and base disk

  - by Henrik

  Hi, I have a virtual machine with about 30 snapshots in branches. The current development path is 22 snapshots plus the base disk. The amount of files is seemingly having an impact now on IO and the dev laptop I'm using (don't know if it is host disk performance issues with the 140GB total size over a lot of fragments, or just the fact that it is hitting sectors distributed across a lot of files). I would like to merge the current development branch of snapshots together with the base disk, but I am unsure if the following command would produce the correct outcome. I am not able to boot this disk after the procedure completes (5-6 hours). vboxmanage clonehd "C:\VPC-Storage\.VirtualBox\Machines\CRM\Snapshots\{245b27ac-e658-470a-b978-8e62137c33b1}.vhd" "E:\crm-20100624.vhd" --format VHD --type normal Could anyone confirm if this is the correct approach or not?

• Outgoing only SMTP server

  - by Din

  I want to setup on my Debian outgoing only SMTP server, so my Web-applications will be able to send mail via it. I don't want to use other hosts because of security and customizability of my own setup. I want to setup Postfix and configure it only in outgoing mode (I don't want it to be a relay). So I want to ask an advice how to do it in the best way. There's no need in users, virtual users, endpoints and other options that Postfix provides. I suppose that I should only attach Postfix to some hostname so my IP address can resolve to it. I also think that Postfix maybe a bit complicated solution for this task. If you know much simpler tool for it, let me know. Thanks.

• Managing MS Exchange server-side email rules on Mac OS X?

  - by Doug Harris

  Has anybody found an easy way to manage server-side rules from Mac OS X? Here's a brief list of what I know doesn't work: Entourage 2008 - it supports client rules, but not server rules. No good, there are certain actions that should happen before I open my laptop or check my email on my iPhone. Apple Mail - same as Entourage, but at least I don't get as frustrated since, unlike Entourage, this isn't a Microsoft product. Web mail (aka Outlook Web Access) - perhaps you can manage rule in the fancy version which Exchange serves to IE, but not with the browsers available on a Mac. I manage this now by launching a VMWare virtual machine running Windows XP and Outlook. I don't count that as an easy way. Update, post release of Office 2011 Does MS Outlook 2011 have the ability to manage server-side rules? Update, post installation of Office 2011 No. Outlook 2011 doesn't have this ability. I've already removed my account from Outlook and switched back to Apple Mail and iCal

• IIS slow response

  - by Martin Ševic

  I have developed ASP.NET 4.5 application which take infos about sensors from sqlite database every 3 seconds. This application runs nice on my local develop machine on IIS Express server. I have created virtual machine (4x 3,25 GHz CPU; 6GB RAM) where i have installed Windows Server 2012 and IIS 8 service in order to test application on real server because we will run it on production machine later. After installing VC++ 2010 x64 and VC++ 2010 x86 and set "Enable 32-bit application" to true in application pool website started to work but there is a large problem with response time. There is a for example 10 seconds delay before page loads. CPU utillization is about 10% and RAM about 1,5GB. I am new to configuring IIS server so i want to ask if there is some tip how to make it faster. I am sure, there will be some twist which will make it normal work. Many thanks.

• IPTables: allow SSH access only, nothing else in or out

  - by Disco

  How do you configure IPTables so that it will only allow SSH in, and allow no other traffic in or out? Any safety precautions anyone can recommend? I have a server that I believe has been migrated away from GoDaddy successfully and I believe is no longer in use. But I want to make sure just because ... you never know. :) Note that this is a virtual dedicated server from GoDaddy... That means no backup and virtually no support.

• What is OpenSVC?

  - by sh-beta

  OpenSVC was just ported to the FreeBSD platform. The little blurb in that announcement intrigued me so I went to the OpenSVC website and found this: OpenSVC is a 'service' manager, as in clustered service manager, designed for real-world heterogeneous datacenters and large-scale operations orchestrator (disaster recovery, for example). Services are collections of resources (virtual machine, ip, disk groups, filesystems, file synchronizations, and application launchers). Services can be started, stopped and queried for status, providing a consistent command set for wildly different service integration types. Service configurations, status and logs are pushed to a central database coupled to a web front-end (collector). Services can be administered using the stand-alone GPLv2 software stack deployed on the nodes (nodeware), or through the web-front end. Plus some UML-type graphics. Which is all neat, but I still don't understand: what does it do? Am I just being dense? What's the use case for this system?

• Package temperature above threshold, cpu clock throttled

  - by drN

  I am running 64 bit Ubuntu 11.10 on an i7 with 8gigs of ram. I thought of putting this on askubuntu.com but decided that maybe the question has a much broader appeal. I have the following error message popping up when I run math simulations. CPUn: Core temperature above threshold, cpu clock throttled (total events = xxxxxxx) CPUn: Package temperature above threshold, cpu clock throttled (total events = xxxxxxx) I realize that this is a hardware warning message (machine check exception, correct me if I am wrong). How do I turn these messages off? Since it doesn't seem to have a detrimental effect of my calculations or my computer (presumably), I don't like it cluttering up my virtual console screen with hundreds of these messages.

• Difference between SSLCertificateFile and SSLCertificateChainFile?

  - by chrisjlee

  Normally with a virtual host an ssl is setup with the following directives: Listen 443 SSLCertificateFile /home/web/certs/domain1.public.crt SSLCertificateKeyFile /home/web/certs/domain1.private.key SSLCertificateChainFile /home/web/certs/domain1.intermediate.crt From: For enabling SSL for a single domain on a server with muliple vhosts, will this configuration work? What is the difference between SSLCertificateFile and SSLCertificateChainFile ? The client has purchased a CA key from GoDaddy. It looks like GoDaddy only provides a SSLCertificateFile (.crt file), and a SSLCertificateKeyFile (.key file) and not at SSLCertificateChainFile. Will my ssl still work without a SSLCertificateChainFile path specified ? Also, is there a canonical path where these files should be placed?

• Connecting to iSCSI Target

  - by Joost Verdaasdonk

  I've installed Microsoft iSCSI Software Target 3.3 on a server 2008 R2 machine and created a new iSCSI Target. In the target I created a new Virtual Disk. From another server I started iSCSI Initiator and in Targets | Target I typed the IP of the Target. (Also tried DNS name.) But when I click Refresh I never see the target. Through googling I found this Youtube tut from a French guy doing pretty much what I did (only difference is I'm in a domain). I first though that maybe Port 3260 was closed but its not I can telnet to it. Also disabled all firewalls to see if that was blocking anything... No luck so far. Does anybody know of possible reasons why I can't connect to the iSCSI Target? If I can provide more info please let me know what's needed? Extra info: I've used this tut to set things up.
