I'm not familiar with kvm but is this a 32 bit guest you are trying to assign more than 3.9 gigs to? if so that may be why it is not working.

I try to add a new guest into my KVM RHRL 5.5 x86_64 server. This server has 32G of memory and currently all other guests are not running.

When using the command line virt-install with 4G ( or more ) of memory for the guest as the below command, I get the error "could not query memory balloon allocation". When I change it to 2048 or 3072 the command works fine.

Using virt-manager ( the X interface ) to add a new guest with startup memory of 8G works fine too.

(Note : this is a KVM ( not Xen ) server. The server and LVs get their names from the previous installation)

Any advice is greatly appreciated.

Thanks,
