Kernel panic when trying to provision kvm virtual server onto nfs drive

[William King]

I can reproduce the bug easily. I just try to provision a virtual kvm server onto a nfs mounted share. It gets to the point: 2009-09-07 16:36:28,372 INFO Converting /tmp/vmbuilderPlvwcH/disk0.img to qcow2, format /mnt/kvm/virtservers/testing/disk0.qcow2
2009-09-07 16:36:28,372 DEBUG ['/usr/bin/kvm-img', 'convert', '-O', 'qcow2', '/tmp/vmbuilderPlvwcH/disk0.img', '/mnt/kvm/virtservers/testing/disk0.qcow2']

Then it kernel panics.

Fixed. the issue was dead ram. 2 of the 4 sticks were bad, and it happened to be 2GB -4GB ram, so it was only happening when transfering large amounts of data, which used the upper ram.

Please mark this bug as invalid. It was bad ram.

Hi William,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 426014

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
