Unable to create HVM or PV domUs with Xen 4.1

[Hugo Silva <hugo%barafranca.com@localhost>]

Hello everyone,

I'm sorry if this has been covered before, in which case please point in
the right direction. I did search the archives, but didn't find anything
relevant.


# xl create freebsd.conf

That's how far it goes.
In /var/log/messages, I see:

xenbackendd[1885]: can't exec /usr/pkg/etc/xen/scripts/block: No such
file or directory
syslogd[184]: last message repeated 4 times

In qemu-dm-freebsd.log:

The config file I'm using is a slightly adapted version from a working
xen3 config:

kernel = "hvmloader"

builder='hvm'
memory=2560
shadow_memory=16
name="freebsd"

vif = [ 'mac=xx:xx:xx:xx:xx:xx, bridge=bridge0, model=e1000' ]

disk =  [
    'phy:/dev/mapper/vg0-freebsd,hda,w',
    'phy:/dev/mapper/wd1_swapvg0-freebsd_swap0,hdb,w',

'file:/usr/pkg/etc/xen/iso/FreeBSD-8.2-RELEASE-amd64-disc1.iso,hdc:cdrom,r'
    ]

boot="d"

vnc = 1
sdl = 0

vncconsole=0
vncdisplay=0

cpus=[ "1", "2" ]
vcpus=2
keymap="pt"

acpi=1
apic=1
device_model='qemu-dm'
stdvga=0
serial='pty'0





A (netbsd) PV domain started with xl shows the following in messages:

xenbackendd[2760]: can't exec /usr/pkg/etc/xen/scripts/block: No such
file or directory
syslogd[184]: last message repeated 5 times
xenbackendd[2840]: can't exec /usr/pkg/etc/xen/scripts/vif-bridge: No

such file or directory
xenbackendd[307]: Failed to read
/local/domain/0/backend/console/4/0/script (No such file or directory)



It seems the failures are related to the usual scripts not being around
anymore.

What would be the proper way to launch HVM/PV VMs with 4.1?

Thanks in advance for any help.
