[Xen-community] trouble launching vm''s

Hello,

 I must be missing something very very basic. Because I am having
trouble launching some vm''s that I recently built whereas I
don''t have
any problem at all launching some older images I made in very much the
same way!

 First there is vm01 which works just fine:

[root@lcent5-1:/etc/xen]$:xm create vm01
Using config file "./vm01".
Started domain vm01
[root@lcent5-1:/etc/xen]$:


And here is the conf file for vm01:

name = "vm01"
uuid = "4d996e30-dbce-4717-dbc6-8fa149ddf96b"
maxmem = 256
memory = 256
vcpus = 1
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
disk = [ "tap:aio:/vm/vm01.img,xvda,w" ]
vif = [ "mac=00:16:36:3a:88:ae,bridge=xenbr0,script=vif-bridge" ]


So far so good!

But when I try to launch vm05 this is what I get:

 [root@lcent5-1:/etc/xen]$:xm create vm05
Using config file "./vm05".
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!
Usage: xm create <ConfigFile> [options] [vars]

Create a domain based on <ConfigFile>.

Options:

Then it lists some help options.

 I can''t quite figure out why the second and subsuquent vm''s
won''t
launch, because as I said they were built in exacltly the same way!

 Here is the conf file for vm05:

name = "vm05"
uuid = "6830ef63-88e9-69f4-be44-7a71efd4dfa4"
maxmem = 256
memory = 256
vcpus = 1
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
vfb = [ "type=vnc,vncunused=1,keymap=en-us" ]
disk = [ "tap:aio:/vm/vm05.img,xvda,w" ]
vif = [ "mac=00:16:36:2a:0d:dd,bridge=xenbr0,script=vif-bridge" ]


The only difference I can tell between the two is the name of the
vm''s. Can someone please let me know how to proceed to get vm05 and
the others (which have a similar problem) launched?


Thanks!
Tim

try running pygrub /vm/vm05.img

see if it spits out a similar error.

Another thing to try is mount the vm05.img to make sure it contains a
grub config file in / or /boot of that disk image.

Hope that helps.

Re: [Xen-community] trouble launching vm''s

As I can see from error message, your VM (#1) have
no /boot/grub/menu.lst. I think, you can or install kernel/grub/modules
to guest machine by mounting it and chroot''ing, or (I think, this is
more easy) - use external kernel/initrd files.
