XenServer 6.5
Hi all,
We recently experienced a host crash on XenServer 6.5 (all available
patches applied) when running snapshot of the virtual machines disks and
memory. Snapshots of disks only (not memory) does not cause a XenServer
crash. This happens both when initiating the snapshots from CloudStack 4.5
or directly from XenServer/Center.
We are able to reproduce this with Ubuntu 14.04.2 and xe-guest-utilities
6.5.0-1400, XenServer 6.5 with all available patches and FC as primary
storage. We will continue to test with other versions/combinations.
Could someone else with XenServer 6.5 please try a full snapshot of VM with
disks and memory to see if you experience the same? We have the crash dumps
and will report this but it would be useful with some more feedback.
Thanks,
-thinktwo

Hi,
Dynamic scaling does not matter.
We didn't notice any problems with hosts.

Re: XenServer 6.5

Tomasz:
Did you have dynamic scaling and HVM enabled for the Ubuntu 14.04 template
you tested with? If we change the OS-type to Ubuntu 12.04 (PV) or disable
dynamic scaling everything works as it should.
The disabling of intremap didn't solve this for us so we have locked the
issue down to affect snapshot w/memory / live migration for Ubuntu 14.04
(HVM). The hosts still crashes like earlier but no crash dump / kernel
panic is logged like earlier. We managed to get the data from serial port
so we have a case filed for this. However it would be very interesting to
know if this also affect others.

Yep! Btw, the host are HP ProLiant BL460c Gen9 so anyone with a similar

Thanks for testing and feedback. I suppose you are using the tools provided
with XS 6.5 as well?
I have sent our crash dumps to Citrix and are awaiting their analysis. Will
update with the root cause when it's found.

Re: XenServer 6.5

Thanks,
We are running a build based on 4.5.1. Snapshots with memory (from
CloudStack or XenCenter) and a revert works as expected with a CentOS 6.6
install and XenServer 6.5 and the same version of xen-guest-utilities.
I also just tested with a new install of Ubuntu 14.04.2 LTS from running
kernel 3.16.0-30-generic #40~14.04.1-Ubuntu with a new installation of
xe-guest-utilities_6.5.0-1400_amd64.deb installed (from Xens xs-tools.iso)
and the XenServer 6.5 hosts running the VM still crashed when taking
snapshot with memory.
It would be very interesting to know if you also experience this behavior
so let me know when you have had time to test it.

Hi,
This is really scary. Can test within couple of days, but I will put 4.5.1 version as 4.5 is broken. Memory snapshots are not available for the XenServer as far as I know, but they just failed at CS before. Host did crash definately.
Vadim.

Hi all,
We recently experienced a host crash on XenServer 6.5 (all available patches applied) when running snapshot of the virtual machines disks and memory. Snapshots of disks only (not memory) does not cause a XenServer crash. This happens both when initiating the snapshots from CloudStack 4.5 or directly from XenServer/Center.
We are able to reproduce this with Ubuntu 14.04.2 and xe-guest-utilities 6.5.0-1400, XenServer 6.5 with all available patches and FC as primary storage. We will continue to test with other versions/combinations.
Could someone else with XenServer 6.5 please try a full snapshot of VM with disks and memory to see if you experience the same? We have the crash dumps and will report this but it would be useful with some more feedback.
Thanks,
