Re: Freebsd image from Qemu hangs on booting in KVM

I am trying to reproduce this on another setup, and do not see the issue.
My understanding is to run KVM + Qemu, I only need to install KVM modules,
and Qemu does not need to be modified. Is that correct?
[root@ipg-virt01 anjali]# lsmod | grep kvm
kvm_intel 87016 0
kvm 211496 1 kvm_intel
[root@ipg-virt01 anjali]# modprobe -l 'kvm*'
And then I run Qemu, as I did, before installing KVM. It should just use
KVM? Is there any way I can check?
Btw, when it hangs, I cannot even press any key, so not sure how I can get
those commands you suggest below..
