My first vnc config used with xm, which is taken from xen examples:

vfb = [ 'vnc=1,vnclisten=,vncunused=1']

Later I found out this is not for HVM. So I change to:


It solves the vnc problem.

As for serial, I use serial='pty', too. It works fine with qemu-dm
from xen-tools. However, it is not working when I use upstream QEMU.
The upstream QEMU doesn't write anything in
/local/domain/DOMID/serial/0/tty . If I manually write this entry, xl
console will work as expected.

Also I found that HVM creating process hangs from time to time. Log reads

(XEN) HVM12: HVM Loader
(XEN) HVM12: Detected Xen v4.2-unstable
(XEN) HVM12: Xenbus rings @0xfeffc000, event channel 2

I can not reproduce this behavior. If I have further investigation, I
will report it on the list.
