You can use 'hosted-engine' to access the VM over VNC. Usual advice will be to redeploy the engine and restore from backup. You won't loose your VMs and restore will be fast. Powering VMs manually is a tricky part. You can find each VM's configuration file in the vdsm log on the host where the VM was powered on. I used the following in order to repair (yes, I really mean it) my HostedEngine VM, but is valid for all VMs. In order to use virsh, you can use this alias: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' Once you have the VM's xml (from vdsm log or from a backup of the qemu/kvm dir) you can define the VM - virsh define /path/to/xml Next save this file and define the network: <network> <name>vdsm-ovirtmgmt</name> <uuid>8ded486e-e681-4754-af4b-5737c2b05405</uuid> <forward mode='bridge'/> <bridge name='ovirtmgmt'/> </network> virsh net-define vdsm-ovirtmgmt.xml Keep in mind that if you defined a lot of networks, you will need them all, or you have to modify the VM's xml. Last is to mount your storage as oVirt would do.The problem is that you use iSCSI and I can't help with that. I guess if you used iscsiadm to connect your initiator - everything should be fine. The following is for FILE-based storage (which is not your case): You can check <ovirt-vm:leasePath> & <ovirt-vm:path> in the xml. Once you mount the storage and try to power up the VM, libvirt will tell you (in the log) where exactly it is expecting a symlink to exists. It points to the path of the storage for the VMs. Best Regards, Strahil Nikolov На 7 юли 2020 г. 19:34:44 GMT+03:00, Patrick Lomakin <patrick.lomakin(a)gmail.com&gt; написа: >I changed the BIOS Type settings in the cluster settings section to >UEFI BIOS, and hosted-engine does not start after rebooting.
