[PTLsim-devel] Problem of creating ptlvm

Sun Jul 22 18:31:28 EDT 2007

Hello,

I was able to boot the Xen kernel with PTLsim/X extensions, but not able to
create the sample virtual machine ptlsim. I can see "-ptlsim" in
/sys/hypervisor/properties/capabilities. "xm list" shows Domain-0 is running.
The following is the messages from /var/log/xen/xend.log after trying "xm create
ptlvm -c" .
