Xen users - Oct 2009 - i have question about domain-U''s full virtual install

I install my domain-U with virt-install
 virt-install -n SN244_Test_Test44 -r 8192 --vcpus=16 -f /dev/vg01/44root -f
/dev/vg01/44swap -f /dev/vg01/44var -f /dev/vg01/44data -m 00:16:3e:61:63:63
-b xenbr0 --nographics --accelerate --os-type=linux -l
http://172.16.2.45/64/5.3 -x
"kshttp://172.16.1.111/myinstall/new/newd1.ks.cfg"
get the error
virDomainCreateLinux() failed POST operation failed: (xend.err ''Error
creating domain: Unable to find number for device (None)'')
Domain installation may not have been
 successful.  If it was, you can restart your domain
 by running ''virsh start SN244_Test_Test44''; otherwise, please
 restart your installation.

(I haven''t used virt-install for a while so my skills on that is
probably rusty).
I''m not sure HVM domU can load kernel and initrd from a http install
(it supports disk, cdrom, floppy, and PXE boot). What you MIGHT be
able to do for HVM:
- create a boot ISO containing kernel and initrd. For RHEL/Centos, you
can simply use CD1 and boot with "linux askmethod" later. Other
distros might have a special ISO for installing from network.
- create your domU with somthing like this (note I''m omitting some
args which might be unsupported, already the default, or unnecessary)

virt-install -n SN244_Test_Test44 -r 8192 --vcpus=16 -f
/dev/vg01/HVMdisk -l /path/to/your/cdrom-boot-image.iso

- boot with "linux askmethod" (or whatever method your distro needs to
specify http install source). You can also specify kickstart here if
needed.

Hope that helps.
