Hi, What config file format do you have? A xml file, the native xen config file (just a check of python code) or the config.sxp format? You''ll need to get xend to recognise the config file first, and to do that you''ll need to import it. virsh has a number of tools to help with that - if you have a python config, you can do a virsh domxml-from-native config.file> config.xml&& virsh define config.xml If you have the config.sxp format, I''m afraid I''ve got no clue how to help you - From what I understand it''s a copy of the stuff in xenstore, so I''m not sure if you can simply create a folder with the domU''s uuid and move the config file there and expect it to work. You could try creating a native xen config file from the examples in /etc/xen, and just specify the disk image to use, then just do a xm start config.file Hope that helped.. - Kyle On 26/11/2011 3:12 PM, Antonio Colin wrote:> Hi Guys, > > I have Debian 6 + Xen 4.1.1 and created a DomU with virt-manager after > creation: > > laptopvm:~# xm list > Name ID Mem VCPUs > State Time(s) > Domain-0 0 1024 1 > r----- 729.1 > centos-4 512 > 1 0.0 > laptopvm:~# > > Its config file is in: > /var/lib/xend/domains/c0e57693-78a5-0a0b-89b6-93034535ab5a/config.sxp > > Then I did a P2V of another OS and I have the *.img file and the > config file but I > can''t get Xen recognize it as another domU. > > How can I make Xen/Xend do that as well as generate the UUIDs for the > domU''s devices in its config.sxp file ? > Any useful commands? > > Regards, > Tony. > > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi Kyle,
Sorry for late reply but I was trying this, finally I got this error:
root@neutrino:~# virsh -c xen:/// domxml-from-native xen-xm winxp.cfgerror:

My config file is Python format and it''s here:
http://pastebin.com/yc9qBSSJAnd the libvirt and hypervisor versions I am using
are these:

Hi,
What config file format do you have? A xml file, the native xen
config file (just a check of python code) or the config.sxp format?
You''ll need to get xend to recognise the config file first, and to
do that you''ll need to import it. virsh has a number of tools to
help with that - if you have a python config, you can do a
virsh domxml-from-native config.file > config.xml && virsh define
config.xml
If you have the config.sxp format, I''m afraid I''ve got no
clue
how to help you - From what I understand it''s a copy of the stuff
in xenstore, so I''m not sure if you can simply create a folder
with the domU''s uuid and move the config file there and expect it
to work. You could try creating a native xen config file from the
examples in /etc/xen, and just specify the disk image to use, then
just do a xm start config.file
Hope that helped..

Hi Tony, Those errors look like something's wrong with libvirt - http://wiki.libvirt.org/page/FAQ#error:_Unknown_Failure mentions that the "Unknown failure" messages are a result of bad error reporting in libvirt, but says more details should be available in dmesg and /var/log/messages.log Those libvirt versions are quite old though - I'm guessing Debian 6 is the stable release? http://packages.debian.org/stable/libvirt-bin says the version is still 0.8.3-5+squeeze2, when the latest release is 0.9.7 (http://libvirt.org/sources/) Any chance of using a backport? http://packages.debian.org/squeeze-backports/libvirt-bin is 0.9.6, so that might work better. I'm just wondering about the Xen API line - 4.0 to 4.1 made a number of changes, so I don't know what 3.0.1 to 4.1.0 would be like, and I'm thinking that might be the source of the errors. That said - your config file is a standard Xen config file, so it's strange that it'd be in /var/lib/xend/domains. You can get around virsh to at least see if it starts - Put the config (or a copy) in /etc/xen, and try xm create -c /etc/xen/filename. That should at least get Xen starting the domU, but not managing it yet. - Kyle On Thu, Dec 1, 2011 at 5:40 AM, Antonio Colin <dftonywhite@hotmail.com> wrote:> Hi Kyle, > > Sorry for late reply but I was trying this, finally I got this error: > > root@neutrino:~# virsh -c xen:/// domxml-from-native xen-xm winxp.cfg > error: Unknown failure > root@neutrino:~# virsh domxml-from-native xen-xm winxp.cfg > config.xml && > virsh define config.xml > error: Unknown failure > root@neutrino:~# > > My config file is Python format and it's here: http://pastebin.com/yc9qBSSJ > And the libvirt and hypervisor versions I am using are these: > > root@neutrino:~# virsh version > Compiled against library: libvir 0.8.3 > Using library: libvir 0.8.3 > Using API: Xen 3.0.1 > Running hypervisor: Xen 4.1.0 > root@neutrino:~# > > Thank you, > Tony. > ________________________________ > Date: Sun, 27 Nov 2011 10:14:42 +0800 > From: kyl191@kyl191.net > To: dftonywhite@hotmail.com > CC: xen-users@lists.xensource.com > Subject: Re: [Xen-users] How to make a P2V domU be recognized by Xend > > > Hi, > What config file format do you have?

Hi Kyle, Thanks so much for your time and advice, I must say it''s been far much helpful and I appreciate it. I have upgraded to the most recent version of libvirt for AMD64 architecture which is 0.9.2-7(http://packages.debian.org/squeeze-backports/amd64/libvirt0/download) and this is the result: root@neutrino:~# virsh versionCompiled against library: libvir 0.9.2Using library: libvir 0.9.2Using API: Xen 3.0.1Running hypervisor: Xen 4.1.0root@neutrino:~# The UNIX socket interface is enabled: (xend-unix-server yes). No clue about the Xen API line yet. Here is a new phenomenon though:root@neutrino:~# virsh -c xen:/// domxml-from-native xen-xm winxp.cfg > config.xml error: An error occurred, but the cause is unknownroot@neutrino:~# As you''ve perfectly described I can actually start the domain using: #xm create winxp.cfg. And again, the control is managed by xm and # virsh list --all doesn''t show anything. Virsh cannot create the domain since it is not in an XML format nor can it start it because it is not a libvirt managed domain. There are no last entries either in /var/log/messages or /var/log/libvirt/libvirtd.log. Virsh and virt-manager are working fine and can indeed connect to the hypervisor. And just one last question: remus (for HA), is independent of all the libvirt management and workarounds? I mean, can I use both things at the same time?, because I see virsh / virt-manager can in fact migrate domains, but it is just live-migration and not intended for HA. Thank you once again!

Hi Tony, I just tried converting your linked config file myself. I''m getting the same error message as you, so it seems to be a bug in virsh/libvirt.

I''m going to poke around a bit more with the libvirt debug options when I get back from a trip on Sunday, and based on the results of that I might file a bug in Fedora too. One thing you might be able to try - run "xm new config.file". It''s listed under "Common ''xm'' commands" as " Adds a domain to Xend domain management". That might get it into libvirt/virsh, it might not. On my system it''s not working, complaining about "No module named lxml", so I need to go find the module & install it. As for your Remus question, I''ve never used Remus before, but as far as I know, Remus + Xen/libvirt can be run independently. At one point in time there was mention of being able to specify a disk like ''phy:remus:/dev/vg/lv'' in your domain config file, and Xen would take care of some configuration options, but I''m not sure what happened to it.

Hello Kyle,
I hope you are having a good day, I have just submitted the bug report to
Debian libvirt maintainers and awaiting further information. I did exactly what
you suggest and in fact it worked in the end :D.The error: ImportError: No
module named lxml also was an issue to me but I tried this:
# dpkg -i python-lxml_2.2.8-2_amd64.deb
It finishes with errors but #xm new is able to work, I am afraid my python2.6 is
not yet properly configured though.I''ve pasted a complete output of
this to convert to XML here: http://paste.debian.net/147767/ Fortunately it got
into libvirt :). I will start now to test remus on this and see if I need the
option you mention.
I think that is everything, so Kyle thank you for you much appreciated help, it
would have been far more difficultwithout you.
By the way, enjoy your trip! ;)
Tony.

Hi Tony,
I just tried converting your linked config file myself. I''m getting
the same error message as you, so it seems to be a bug in
virsh/libvirt. For the record, this is my system:
[root@elemental log]# virsh version
Compiled against library: libvir 0.9.6
Using library: libvir 0.9.6

I''d suggest filing a bug in Debian and attaching your config file

a reference. I''m going to poke around a bit more with the libvirt
debug options when I get back from a trip on Sunday, and based on
the results of that I might file a bug in Fedora too.
One thing you might be able to try - run "xm new config.file".
It''s
listed under "Common ''xm'' commands" as "
Adds a domain to Xend
domain management". That might get it into libvirt/virsh, it might
not. On my system it''s not working, complaining about "No
module

As for your Remus question, I''ve never used Remus before, but as
far
as I know, Remus + Xen/libvirt can be run independently. At one
point in time there was mention of being able to specify a disk like
''phy:remus:/dev/vg/lv'' in your domain config file, and Xen

Hopefully someone has a known-accurate answer.
Good luck!

Hi
Kyle,
Thanks
so much for your time and advice, I must say it''s been far
much helpful and I appreciate it.
I have upgraded to the most recent version of libvirt for AMD64
architecture
which is 0.9.2-7
(http://packages.debian.org/squeeze-backports/amd64/libvirt0/download)
and this is the result:
root@neutrino:~#
virsh version
Compiled
against library: libvir 0.9.2
Using
library: libvir 0.9.2
Using
API: Xen 3.0.1
Running
hypervisor: Xen 4.1.0
root@neutrino:~#
The
UNIX socket interface is enabled: (xend-unix-server yes). No
clue about the Xen API line yet.
Here
is a new phenomenon though:
root@neutrino:~#
virsh -c xen:/// domxml-from-native xen-xm winxp.cfg >
config.xml
error:
An error occurred, but the cause is unknown
root@neutrino:~#
As
you''ve perfectly described I can actually start the domain
using: #xm create winxp.cfg. And again, the control is
managed by
xm and
# virsh list --all doesn''t show anything. Virsh cannot
create the domain since it is not in an XML format nor can
it start it
because
it is not a libvirt managed domain.
There
are no last entries either in /var/log/messages or
/var/log/libvirt/libvirtd.log. Virsh and virt-manager are
working fine and can
indeed
connect to the
hypervisor.
And
just one last question: remus (for HA), is independent of
all the libvirt management and workarounds? I mean, can I
use both things
at the
same time?, because I see
virsh / virt-manager can in fact migrate domains, but it is
just live-migration and not intended for HA.
Thank
you once again!
Tony.
