Could not send the import converted instance command to host #11208
Description
problem
Cloudstack 4.20.1
2 KVM hosts RHEL 8.10 (24 cores, 256GB)
1 management server RHEL 8.10
1 Zone - Core, networking advance share network
vCenter 7.0, ESXi 6.5
External vCenter trying to import unmanaged VM.
trying to import a VMware instance to cloudstack. Simple small VM running RHEL 8.10 on VMware imports fine and I can log into it from pulblic network. But while trying to import a VMware VM with 16 coress and 256GB RAM and 1.5TB of storage fails with below error. I can see the qcow2 images under primary storage and in logs I can see the drives were imported and converted. After that it tried to start the VM on KVM host (I am assuming) and fails after 3600sec.
