I have a Fedora 15 x86_64 system, 8 GB of RAM, 4 CPUs, 1 terabyte
disk. I run several virtual machines on it, used to check
cross-system compatibility of some software I develop for my employer.
I run "yum upgrade" on the host every work day, so it is up to date
as of today (August 31).
I have a RHEL 6.1 guest that I am using very heavily right now. I run
it with virt-manager. The guest's disk is a logical volume with no
(host) filesystem. The guest's memory is drawn from a 1 GB hugetlbfs.
The host has a Nehalem CPU, which is exposed (to the extent possible)
to the guest. The display uses spice + qxl drivers in the guest.
Recently, the guest has gotten stuck from time to time. I'll be
typing away and suddenly the guest's display will freeze. When this
happens, I can still use the mouse to perform functions on the host,
but pressing keys has no effect. Exactly 150 seconds later, the guest
will unfreeze (sort of; see below) and I can change keyboard focus to
other host applications again. At that point, the guest window will
*partially* repaint, but will still not change in response to mouse or
keyboard actions. I have to close that window and then click in
virt-manager to open a new window. At that point, I can see that all
of the key presses I made while it was frozen were received and acted
on by the guest, so it is only the display that froze.
I have other Linux guests. None of them display this behavior. Is
this some kind of incompatibility between the RHEL 6.1 qxl drivers and
Fedora 15 spice? Does a 150 second timeout ring a bell with anyone?
Is there some way to get the keyboard focus away from the guest when
this happens so I can at least do something useful on the host?
Thanks,
