Ovirt HE has to be redeployed on a CentOS/EL 8 system and restored from backup. >2) Install CentOS 8.2 and oVirt node 4.4 on new server (let’s name it >node #3). >3) Migrate virtual machines from old node #1 to the new (#3). >4) Upgrade CentOS on old node #1 to v8.2, and oVirt from web interface. >Will that work, or upgrade CentOS 7 -> 8 will render this process >unmanageable due to removal of many components?

I would recommend you to create 3 VMs on your Ovirt (with nested Virtualization enabled) and test your plan on those VMs. >Thanks in advance for any suggestion(s) > >with best regards >Andrei >_______________________________________________ >Users mailing list -- users@ovirt.org >To unsubscribe send an email to users-le...@ovirt.org >Privacy Statement: https://www.ovirt.org/privacy-policy.html >oVirt Code of Conduct: >https://www.ovirt.org/community/about/community-guidelines/ >List Archives: >https://lists.ovirt.org/archives/list/users@ovirt.org/message/B6TKPHULJE37CF2O44FJJVJ3KOXR5IZI/ _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/JFZ3AB53YXXMZEAJXQDWX35JKKXS7IVO/
