@Gunseerat can you check whether you have selected the hypervisor type as KVM while adding cluster and host?

[weizhouapache]

@Gunseerat
do you use a non-root user ?

[Gunseerat]

@rajujith yes sir the hypervisor is kvm selected while creating host
@weizhouapache I have added all permissions in sudoers file also

[Gunseerat]

I do not understand what server resources is it referencing to...

[weizhouapache]

@rajujith yes sir the hypervisor is kvm selected while creating host @weizhouapache I have added all permissions in sudoers file also

@Gunseerat
and wheel group as well ?
refer to #8851 (comment)

[yadvr]

same as #8851 - looks like kvm setup issue.
