Mount options
by Tommaso - Shellrent
Hi to all.
there is a way to change the mount options of a running storage
domain with gluster, without set all to maintenance and shoutdown the vm
on it!?
Regards,

Issues deploying 4.4 with HE on new EPYC hosts
by Mark R
Hello all,
I have some EPYC servers that are not yet in production, so I wanted to go ahead and move them off of 4.3 (which was working) to 4.4. I flattened and reinstalled the hosts with CentOS 8.1 Minimal and installed all updates. Some very simple networking, just a bond and two iSCSI interfaces. After adding the oVirt 4.4 repo and installing the requirements, I run 'hosted-engine --deploy' and proceed through the setup. Everything looks as though it is going nicely and the local HE starts and runs perfectly. After copying the HE disks out to storage, the system tries to start it there but is using a different CPU definition and it's impossible to start it. At this point I'm stuck but hoping someone knows the fix, because this is as vanilla a deployment as I could attempt and it appears EPYC CPUs are a no-go right now with 4.4.
When the HostedEngineLocal VM is running, the CPU definition is:
<cpu mode='custom' match='exact' check='full'>
<model fallback='forbid'>EPYC-IBPB</model>
<vendor>AMD</vendor>
<feature policy='require' name='x2apic'/>
<feature policy='require' name='tsc-deadline'/>
<feature policy='require' name='hypervisor'/>
<feature policy='require' name='tsc_adjust'/>
<feature policy='require' name='clwb'/>
<feature policy='require' name='umip'/>
<feature policy='require' name='arch-capabilities'/>
<feature policy='require' name='cmp_legacy'/>
<feature policy='require' name='perfctr_core'/>
<feature policy='require' name='wbnoinvd'/>
<feature policy='require' name='amd-ssbd'/>
<feature policy='require' name='skip-l1dfl-vmentry'/>
<feature policy='disable' name='monitor'/>
<feature policy='disable' name='svm'/>
<feature policy='require' name='topoext'/>
</cpu>
Once the HostedEngine VM is defined and trying to start, the CPU definition is simply:
<cpu mode='custom' match='exact' check='partial'>
<model fallback='allow'>EPYC</model>
<topology sockets='16' cores='4' threads='1'/>
<feature policy='require' name='ibpb'/>
<feature policy='require' name='virt-ssbd'/>
<numa>
<cell id='0' cpus='0-63' memory='16777216' unit='KiB'/>
</numa>
</cpu>
On attempts to start it, the host is logging this error: "CPU is incompatible with host CPU: Host CPU does not provide required features: virt-ssbd".
So, the HostedEngineLocal VM works because it has a requirement set for 'amd-ssbd' instead of 'virt-ssbd', and a VM requiring 'virt-ssbd' can't run on EPYC CPUs with CentOS 8.1. As mentioned, the HostedEngine ran fine on oVirt 4.3 with CentOS 7.8, and on 4.3 the cpu definition also required 'virt-ssbd', so I can only imagine that perhaps this is due to the more recent 4.x kernel that I now need HE to require 'amd-ssbd' instead?
Any clues to help with this? I can completely wipe/reconfigure the hosts as needed so I'm willing to try whatever so that I can move forward with a 4.4 deployment.
Thanks!

tun: unexpected GSO type: 0x0, gso_size 1368, hdr_len 66
by lejeczek
hi everyone,
With 4.4 I get:
...
tun: unexpected GSO type
...
It happens to a "third-party" kernel, namely:
5.6.15-1.el8.elrepo.x86_64 on Centos 8.
I wonder if anybody sees the same or similar and I also
wonder if I should report it somewhere in Bugzilla as
"heads-up" towards new kernels?
