RE: [Xen-users] Manual p2v



Do you have SELinux enabled?  If so, you may need to relabel the filesystem:

 

touch /.autorelabel

 

before you boot.

I think I am close to get this converted VM running. When I try to login to domU I am getting login permission denied..

Don't know what is wrong here.

 

Thanks!

Here is where I am stuck at:

 

I have a xenifed kernel installed for the PV. When I do: xm create domUname -c

 

I get this:

[root@cvtst1 ~]# xm create centos1 -c

Using config file "/etc/xen/centos1".

Traceback (most recent call last):

Looks like it is not finding kernel, initrd (?)

grub.conf entry is:

title CentOS (2.6.18-194.3.1.el5xen)

          root (hd0,0)

          kernel /xen.gz-2.6.18-194.3.1.el5

          module /vmlinuz-2.6.18-194.3.1.el5xen ro root=/dev/xvda1 console=xvc0

          module /initrd-2.6.18-194.3.1.el5xen.img

config file for domU is:

 

--

[root@cvtst1 vms]# more centos1

name = "centos1"

maxmem = 1024

memory = 256

vcpus = 1

cpus="1-2"

bootloader = "/usr/bin/pygrub"

which part are you confused about? As long as you put the disk image
containing /boot first in your domU config file, pygrub should pick it
up just fine. The more important issue, since you'll be using paravirt
(PV) guest, is to prepare your system so it has PV-compatible kernel
and config (grub.conf, fstab, etc.). See http://pastebin.com/f6a5022bf
for example. The example is for converting HVM domU to PV, but some of
the info should also apply to converting physical machine to PV.
