As the subject states, we just noticed a new kernel was released and updated/rebooted a few of our non-production hosts. They all have the same issue when attempting to start a container. You can't start a container and get this error:
Failed to start the CT: PRL_ERR_VZCTL_OPERATION_FAILED (Details: vcmmd: failed to register Container: Failed to get VCMMD D-Bus name
vcmmd: failed to unregister Container: Failed to get VCMMD D-Bus name
vcmmd: failed to unregister Container: Failed to get VCMMD D-Bus name
Failed to start the Container
)
I noticed that vcmmd.service is stuck "activating", and looking at the vcmmd.log it's failing with this:

Is anyone else running into this? I have the same issue on all 4 hosts that I updated yesterday.
Thanks!,

Another update:
It would appear that the issue is this package causing the issue:
vcmmd.noarch 8.0.88-1.vz7 @openvz-os
I removed vcmmd.noarch (which of course removes a ton of dependencies that I had to manually re-install after), and replaced it with the package from the older release: https://download.openvz.org/virtuozzo/releases/openvz-7.0.20 -147/x86_64
vcmmd.noarch 8.0.77-1.vz7 @/vcmmd-8.0.77-1.vz7.noarch
And now the vcmmd service starts fine, and I've been able to get a container to run on the host, everything seemingly working now. However, there was a huge chain of dependencies that I went through and manually re-installed, and this fix was super "hacky". I'd do it on a production server in a pinch if I had to, but wouldn't feel comfortable running production VPS's on it, so I'm hoping we get an official fix soon.
This does shine some light on where the issue is with the latest release, so hopefully some devs will see this and patch the latest release ASAP. I have 4 hosts that I've updated to the latest release, and this issue has happened on each one of them.
