OMV7 - KVM plugin error

Hello,

I made the switch from OMV6 to OMV7 recently.

Everything reinstalled on a nvme SSD.

Everything works as OMV6 (mergerfs, snapraid, docker, docker-compose).

I have a problem with the KVM plugin, installation is ok with no error. I can create a vm with no problem.

But KVM service is not present on the dashboard services and i got a RPC error when i open the KVM backup or restore menu:

Maybe try a private page or check the rrd cache via omv-firstaid

ryecoaaron is the maintainer of the plugin will be able to make more sense on this.

The STACK TRACE shows where it is failing:

I hope so , did not have this problem on OMV6 with KVM plugin.

You're right, i didn't backup my vm on OMV6 either, maybe i didn't get in this menu...

I thought KVM appears in OMV6 services, bad memories...

Anyway, thanks for your work and the quick answer and fix.

Hi,

new version downloaded, no more error, thanks.
