Hi,
Yes, I've got quite the same issues with RHEL5 guests on oVirt 4.2.3 :
random guest freeze and oVirt host crash while rebooting a guest !
It seems to be a kernel bug introduce with 7.5 :
https://bugzilla.redhat.com/show_bug.cgi?id=1584775
https://access.redhat.com/solutions/3496461
While waiting for this kernel patch, I use an older kernel version on
the oVirt host : 3.10.0-693.21.1.el7 works fine with oVirt 4.2.3 and
RHEL5 guest.
Regards,
Arnaud Lauriou

Hi,
I am experiencing that my RHEL5 guests frequently "hang" when
migrating host. Console is blank, CPU after migration is 100% and as
far as oVirt is concerned, the VM is OK.
oVirt is 4.2.3.8-1.el7, on CentOS 7. Hosts are CentOS 7 as well.
Cluster is in "Intel Westmere family" CPU type.
Guest is RHEL5, fully patched, kernel 4.2.3.8-1.el7 with
ovirt-guest-agent installed from EPEL.
I do not see anything out of place in the ovirt-engine and vdsm
logs, and the guest logs are simply not there, the stop right before
the migration,as if the machine had "frozen".
Powering the VM off and starting it starts the VM correctly. This
does not happen 100% of the time. If I try to migrate the VM when it
is freshly started the migration is faster (maybe 5 seconds), and the
guest OS does not hang.
Anybody else experiencing something similar? Maybe something
(timeouts?) that I should tune on the guest OS for RHEL5?
Thanks!
