Re: [Xen-devel] problem creating a new domain
Hi Folks,
I am using xen1.2.
I create the disk image as described in the Xen2.0 user manual chapter 5.
Sorry but that won't work :-(
Xen 1.2 can only export sections of physical disks (e.g. partitions, whole
disks, or Xen Virtual Disks) to other domains. If you want to store
filesystems in disk files, you should move to Xen 2.0-beta (soon to be Xen
2.0-release).
The nearest you can get on Xen 1.2 is to create a Virtual Disk and then use
that. Tying yourself to 1.2 is probably not a good idea though - Virtual
Disks aren't supported by 2.0. We'd certainly prefer people to move to 2.0
now - it's stable and virtually release-ready and has a whole load of new
features, improved tools and better hardware support.
A good way to install a new domain's filesystem is using debootstrap (as
described in the appendix of the manual).
Let us know how you get on.
HTH,
Mark
#dd if=/dev/zero of=vm1disk bs=1k seek=6144k count=1
#losetup /dev/loop1 vm1disk
#mkfs -t ext3 /dev/loop1
#mount /dev/loop1 /mnt
#cp -ax /<directory>/ /mnt/ /* I do this instead of copying the
whole / directory because I don't want some of the directories in Dom 1 */
I modify /mnt/etc/fstab to put /dev/sda1 to root
# umount /dev/loop1
then I put this line in /etc/xc/defaults (I used a copy of it called
dom1)
vbd_list = [ ('phy:loop1','sda1','w' ) ]
After this I try to create the dom1 by saying but I get an error.
#xc_dom_create.py -D vmid=1 -f dom1
Parsing config file 'dom1'
VM image : "/boot/xenolinux.gz"
VM ramdisk : ""

VM IP address(es) : "130.207.98.36; 169.254.1.1"
VM block device(s) : "phy:loop1,sda1,w"
VM cmdline :

root=/dev/sda1 ro 4 VMID=1 usr=/dev/sda6"
Error looking up phy:loop1
Can someone please help me with this error?
Thanks,
Sanjay
