[Bug 695825] Re: Ubuntu KVM error with guest memory >4gb ram

[Neil Hunt]

I checked (a) and indeed it is enabled (receive "KVM acceleration can be
used"). However, each of the virtual machines had <emulator>/usr/bin
/qemu-system-x86_64</emulator>. I changed several of them to
<emulator>/usr/bin/kvm</emulator>, restarted the VMs, however, the
performance is still dismal and I'm also still getting the error when
setting RAM >4gb, not letting me set the RAM above that amount. I run
essentially the same VM on my MacBook with 2 core and 4gb ram using
VirtualBox, allocating only 1gb ram to the guest, and it flies where
this KVM is excruciatingly slow. Any other thoughts?
