Hi Folks,

Just a word of caution. If you are going to install kasten on Harvester, then use the Marketplace app and don’t do a Helm install with versions after 8.0.1 (did not test any between 8.0.1 and 8.0.5 but the Marketplace has 8.0.1). The problem is that when you go to restore a VM, Kasten can’t parse the CDI version format properly when using its GetCDIVersion function. K10 expects 1.61.0 or something like v1.61.0.

The error occurs in kasten.io/k10/kio/kubevirt/kubevirt.go:571 where function GetCDIVersion couldn't parse the -150600.3.12.1 build suffix in my specific case.

Unfortunately Kasten 8.0.1 seems to have the quick logout problem if you access the WebUI from the VBR Console. So you will just have to put up with that for the time being as it is fixed in later versions.

The Kasten WebUI is where you can do everything you need anyways so this is not a huge issue.
