Hello,
Under NetBSD with Xen 4.1.1 I'm unable to create a DomU PV using xl,
but xl works fine creating HVM domains. Here's the output from xl -v
create <domu>:

Daemon running with PID 1047
It seems like the domain has been created ok, but when I try to
connect to it with xl -v console <domu> or xm console <domu> I get the
following error:
xenconsole: Could not read tty from store: No such file or directory
Also the DomU seem to be using an unexpected amount of CPU Time, and
CPU usage is always at 100%. The config file for the domain is (wich
works with the old xm):
bootloader = '/usr/pkg/bin/pygrub'
vcpus = '1'
memory = '1024'
root = '/dev/xvda2 ro'
disk = [
'phy:/dev/mapper/guests-one,xvda2,w',
'phy:/dev/mapper/guests-oneswap,xvda1,w',
'phy:/dev/mapper/guests-images,xvdb,w',
]
name = 'one'
vif = [ 'mac=00:16:3E:9C:F2:5E, bridge=bridge1' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
I've enabled xenstored debug, but it doesn't seem to be of any help:
Failed to read /local/domain/0/backend/console/6/0/script (No such
file or directory)
Failed to read /local/domain/0/device-model/6/script (No such file or directory)
As a side note, if I start the DomU with xm, I can connect to it
afterwards using xl console <domu>. And finally my xm info:
