I’m not aware of any issue with the virt stack packages in Stream, that edk2-ovmf issue has been fixed few weeks back, the new version is the right one, but maybe you have other outdated packages? Also please refresh host capabilities after each such package change. There also could be a microcode change for IvyBridge that you’ve missed (or intel didn’t fix for your particular cpu)…perhaps it’s good enough to just change the Cluster CPU to SandyBridge instead. > > I'm running latest 4.4.7 and my cluster version is 4.6. > > Best regards > Christoph > > > Am 27.05.21 um 16:26 schrieb Gunasekhar Kothapalli via Users: >> The issue was with edk2-ovmf package update, rolling that package back and >> it started recognizing the CPU and host coming up... tested on one host and >> worked fine. >> >> >> >> Thanks & Regards, >> Gunasekhar Kothapalli >> >> >> From: Nur Imam Febrianto <nur_i...@outlook.com> >> <mailto:nur_i...@outlook.com> >> Sent: Wednesday, May 26, 2021 9:54 PM >> To: k.gunasek...@non.keysight.com <mailto:k.gunasek...@non.keysight.com>; >> users@ovirt.org <mailto:users@ovirt.org> >> Subject: RE: [ovirt-users] Re: CPU Compatibility Problem after Upgrading >> Centos 8 Stream Host >> >> CAUTION: This message originates from an external sender. >> >> Already trying several things, seem kernel update doesn’t make this problem >> happen.
