[one-users] Running VMs listed as zombies on KVM host?

[Dmitri Chebotarov]

Hi,

Something strange is happening with my VMs... 
Below is 'one host show 161' output and it shows that ONE marks running VMs as zombies on the host. It happens to multiple VMs/HOSTs, but now all. I tried to delete ZOMBIES attribute, but few minutes later it's back with the list of running VMs. What would cause this behavior? 

(ONE 4.8)

$ onehost show 161
