Re: VRs swapping with 256 MB RAM

Hi Rene, I've come across issues where vmware side would provision less than 256MB RAM to the guest OS while vCenter would still claim to have reserved/allocated 256MB RAM. I've seen this happen few cases, which is why for 4.11+ VRs on vmware the guest os type selected is 'other linux 64'. Ref

Live migration across different hypervisors is not possible. You could use a tool such as Veeam agent to backup the running VM and then import it as an image to KVM and start it. As the hypervisors use different paravirtualized drivers, you're going to need to do some work to be able to transfe

Without digging into the code, I believe that the VR reports the version and it's matched against the min version. i'm not sure what happens if the version is not reported at all. Is this recent and have you updated the system QCOW2 or systemvm.iso recently? And if so, did you rebuild the rpms,
