Hi,
I have a fedora15 box with a win7 kvm instance that has been running
for some time, but lately it seems to just crash and disappear without
any idea of what happened. It's never happened while I have been using
it, only when the instance is idle.
I usually start the instance using virt-manager, but also start it
just using "virsh start mykvm" then access it using the spicec client.
I can't find any logging information to indicate why this is happening
or how to go about fixing it.
I've tried accessing it using the normal virt-manager client as well
as the spicec client an it doesn't make any difference.
When it crashes, the whole process is gone. Is there something that
could cause it to do this when the system is idle?
I also installed the qxl video drivers
(qxl-win-0.1010-20110308-d9eb3203bd) some time ago, so it could
possibly be related to that.
I thought it might be helpful to have a copy of the qemu XML file:
