Hosted Engine stalled and unable to restart
Hello, We are on an older version (3.x - cannot be specific as I cannot get my ovirt hosted engine up). We experienced a storage failure earlier this evening - the hosted engine was originally installed with this storage domain although we have moved all VM's and disks off of it. The storage was restored and all the VM's are now running, but the ovirt engine is not pinging and is unreachable. I have attempted to locate it on my HV's using 'virsh list --all' but only one of those is taking my credentials - all the others fail to authenticate. Is there a way to locate what the credentials are on each HV since the default is not working? Additionally, is there any other way to locate the hosted engine and restart it directly from a HV? Thank you for your time and consideration. *** *Mark Steele*
Have you tried hosted-engine --vm-start On any of the HVs ? On Wed, 1 Apr 2020 at 02:57, Mark Steele <msteele@telvue.com> wrote:

For the virsh, I use this alias: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' In order to reach the HostedEngine, you need to first assign a console password: hosted-engine --add-console-password --password=pass It should provide you with IP/port for the console connection (I use VNC, but I'm not sure on v3.X). Once you got a connection, you can try to fix the issue. Maybe it's just a bad entry in /etc/fstab . Best Regards, Strahil Nikolov
Thank you all! We were able to locate it on HV-02 and restart it using virsh. This is how we got virsh working on that HV: Virsh Authorization If Virsh is set for Auth If attempting to use any virsh commands and get auth request you will either need the auth credentials or to create your own.Example: $ virsh list Please enter your authentication name: root Please enter your password: error: Failed to reconnect to the hypervisor error: no valid connection error: authentication failed: authentication failed Solution $ saslpasswd2 -a libvirt <username> *** *Mark Steele* CIO / VP Technical Operations | TelVue Corporation TelVue - We Share Your Vision 16000 Horizon Way, Suite 100 | Mt.

Looks like content for ovirt site: https://github.com/ovirt/ovirt-site To get read-only access you can use: virsh -r list Without special configuration. Using read-write access and modifying vms managed by oVirt is asking for trouble. Should be used as a last resort if there is no way to control the vm via oVirt. Nir Best regards,

The auth file is located at /etc/ovirt-hosted-engine/virsh_auth.conf The simple alias: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' Is enough to play with the toys directly :) It's quite handy if you need to play with the HostedEngine VM :) Best Regards, Strahil Nikolov
