Hi,
(Apoloises for earlier false send)
Host: CentOS 5.5
Guest: Ubuntu - maverick on LVM Volume
With Debian Installer specific variables
I am having a horrid time trying to create a guest on my host. I have
tried several method but they all fail for one reason or another. I
have had the most success with `xm create` but the problem I have with
`xm create` is that once the installation process is over and I am
asked to reboot, the dom no longer apepars in `xm list`.
Here is how I have created the guest, the config file is below:
xm create -c myconf.cfg install=true
install-mirror=http://mirror.bytemark.co.uk/ubuntu/
install-suite=maverick
While the guest OS is being installed, I can see it:
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 21880 24 r----- 2485.6
test-03 8 10240 1 -b---- 498.0
When the OS install is complete, I get the message: "Installation is
complete, so it is time to boot into your new system.". I press
continue, the OS shutdown but rather than staying in the xm list as
Shutdown, it does not appear on the list.
If I try `xm create myconf.cfg -c`, I get:
xm create -c myconf.cfg
Using config file "/etc/xen/myconf.cfg".
Error: Bootloader isn''t executable
I move past this error by editing my config and making giving the path
to pygrub (bootloader = ''/usr/bin/pygrub'')
But then I get this traceback:
[root@vega ~]# xm create -c myconf.cfg
Using config file "/etc/xen/myconf".
Traceback (most recent call last):
File "/usr/bin/pygrub", line 682, in ?
chosencfg = run_grub(file, entry, fs)
File "/usr/bin/pygrub", line 536, in run_grub
g = Grub(file, fs)
File "/usr/bin/pygrub", line 203, in __init__
self.read_config(file, fs)
File "/usr/bin/pygrub", line 397, in read_config
raise RuntimeError, "couldn''t find bootloader config file in
the
image provided."
RuntimeError: couldn''t find bootloader config file in the image
provided.
No handlers could be found for logger "xend"
Error: Boot loader didn''t return any data!
I then run pygrub directly on the VM
#pygrub /dev/mapper/VM-live--03--disk
Traceback (most recent call last):
File "/usr/bin/pygrub", line 682, in ?
chosencfg = run_grub(file, entry, fs)
File "/usr/bin/pygrub", line 536, in run_grub
g = Grub(file, fs)
File "/usr/bin/pygrub", line 203, in __init__
self.read_config(file, fs)
File "/usr/bin/pygrub", line 397, in read_config
raise RuntimeError, "couldn''t find bootloader config file in
the
image provided."
RuntimeError: couldn''t find bootloader config file in the image
provided.
Can anyone offer any advice on why the the dom is not visible after
the VM has been created or how I can get past this (py)grub problem?
Thanks in advance,
Dp.
