[ovirt-users] Re: RHEL5 guests frequently hang when migrating host.
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 On 06/27/2018 08:59 AM, Eduardo Mayoral wrote: 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?
