VM Windows Server 2008 R2 Randomly Stops Working and Crashes

[bradjtram]

I have a VM with Server 2008 on it. The machine worked fine until about 2 weeks ago where now every once in a while the machine will just quit. I've checked all the settings, it's nothing setting wise, but the error log does lead me to believe there is something going on with the configuration or something related to VirtualBox.

This virtual NAT controls the internet for a corporate network, so it is important to resolve this, but not dyer.

Here is the recent error log (it's attached), sorry if it's missing anything because of the 128kb limit i had to cut a lot out of it.

Thank you in advance to everyone who reads, or responds. Cheers.

Compress the log and attach the full content (as an attachment)

[Perryg]

Compress or attach?
Use your Windows 7 host to compress the file or Winzip which ever you have.
Attach you have already done with the other file just do the same.

Here you are.

I see a couple of interesting thing I would like to ask you about.
Was the guest created using vmdK or an import?

I see you have io apci enabled but the report says you do not have VMX available:

Code: Select all

00:00:03.164   IOAPIC            <integer> = 0x0000000000000001 (1)

Code: Select all

HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_SVM_NO_SVM

What is the reason?

Finally to your failure:

Code: Select all

Guru Meditation -2701 (VERR_VMM_RING0_ASSERTION)

What was the host doing during the time this happened? Was there a lot of heavy IO?

Lastly a warning about snapshots:

Code: Select all

00:00:03.165   Path   <string>  = "C:\Users\Administrator.WTRSVRWEBWIN01\VirtualBox VMs\WTRSMSNATCP01\Snapshots/{c980fcfd-634a-4894-825b-b58adf352b68}.vmdk" (cb=121)

Since you are using snapshots make sure you are doing reliable backups of the base, snapshots, & config files. In other words backup the folder that has the guest regularly.

This machine was created on the host and the VM disk is VMDK

Code: Select all

00:00:03.164   IOAPIC            <integer> = 0x0000000000000001 (1)

Code: Select all

HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_SVM_NO_SVM

What is the reason?

The host machine is x64 while the nat is 32 bit. I read that IOAPIC was needed to be enabled for the machine to function properly.

Finally to your failure:

Code: Select all

Guru Meditation -2701 (VERR_VMM_RING0_ASSERTION)

What was the host doing during the time this happened? Was there a lot of heavy IO?

The host is not doing anything out of the ordinary. It's home to 2 other VM's The machine has 3 VMS, on two of which that run twenty-four seven, and the other is an on demand machine that boots when it's logged into (but is rarely ever used). as for heavy I/O, i don't believe so. the vms are not using a lot of the host system resources just ram and disk space but it's a quarter (if that) of what the machine has installed. (combined). The machine is a backup webserver, but there is no web traffic unless our main server goes down, and its not been down in about 7 months, so i don't see any record of any internet traffic on the machine.

Lastly a warning about snapshots:

Code: Select all

00:00:03.165   Path   <string>  = "C:\Users\Administrator.WTRSVRWEBWIN01\VirtualBox VMs\WTRSMSNATCP01\Snapshots/{c980fcfd-634a-4894-825b-b58adf352b68}.vmdk" (cb=121)

Since you are using snapshots make sure you are doing reliable backups of the base, snapshots, & config files. In other words backup the folder that has the guest regularly.

I don't use snapshots on these VMs.

Do you recommend that I disable IO APIC?

[Perryg]

I don't know if it (the guest) will allow this since it was installed with it on but worth a try.
You seem to indicate that the machine used to work properly until about 2 weeks ago. Can you tell or find out what has changed?

Nothing has changed in the last two weeks. We haven't updated the machine, or done any maintenance on it. It seems to happen either right after the machine is accessed (then goes idle) or when the machine is at idle for long periods of time.

Not sure if that has anything to do with it.

Thank you for your help

[bradjtram]

When I disabled it, all it did was sit at a blank screen after showing the Post Screen. I'm assuming that's what you were talking about?

[Perryg]

It seems to happen either right after the machine is accessed (then goes idle) or when the machine is at idle for long periods of time.

Make sure that all power saver features are shut off on the guest, including screen saver and NIC and see if this helps.

[bradjtram]

I checked to make sure and there are no settings that make anything shut off when idle, including the NIC.

Would that happen though? Could the nic shutting down potentially crash the machine?

[Perryg]

Probably not but the easiest way to determine is to turn things off and then turn them on one at a time to see which one makes the problem show.

[bradjtram]

this doesnt happen immediately though, it happens anywhere between an hour and upto 6 days after the computer has been started up.

Hi,

I have (as I think) exactly the same issue. It does make the Virtual Box practically useless. At least for the Windows Server 2008 R2 guests.

Here is what happens:

I created a Virtual Machine with default settings for everything except for guest type (Windows 2008 64-bit), file paths, memory, number of processors, disk size (and name, obviously). I installed the Windows Server 2008 R2 onto it using the ISO image downloaded from the microsoft-dot-com. Then I installed Active Directory Role and a Web Server Role.

Additionally I installed a MS Visual Studio 2010 onto it. After running for about one hour the virtual machine window just disappears. Actually, I have never seen it disappear right in front of my eyes. I would work with the developed web-application running on this box. After a while the browser cannot connect to the server. Then, looking at the host computer I find out that the virtual machine is not running any more. On average, it happens after one hour of operation.

First, I thought there was something wrong with the guest system itself. None of the logs or system events provided any clue of what was wrong. I reinstalled the whole system from scratch but the issues persisted. I upgraded the Virtual Box to the latest version 4.1.22, it didn't help. Then I downgraded the version to 4.1.10 (because I didn't have such problems in Spring). I didn't help either. Now I'm stuck with that. I can't use the virtual box.
