Hi,
I am frustrated searching for a quick-start documentation for virsh,
just to no avail. Any help is greatly appreciated!
Here is what I did:
- Compile and install libvirt, virt-manager, virt-install and
virt-viewer from source code. This is done (on Ubuntu 8.04).
- Now I want to do install a new VM with QEMU or KVM. I got the below
error with virt-install:
# virt-install -c qemu:///system --name jeos2 --ram 500 --file
img.jeos2 --cdrom jeos-8.04.1-jeos-i386.iso
Fri, 15 Aug 2008 19:19:10 ERROR virConnectOpen() failed
Traceback (most recent call last):
File "/usr/bin/virt-install", line 496, in <module>

File "/usr/lib/python2.5/site-packages/libvirt.py", line 139, in open
if ret is None:raise libvirtError('virConnectOpen() failed')
libvirtError: virConnectOpen() failed
How to fix this? Perhaps I need to run libvirtd before using virsh???
What frustrates me is that there seems no documentation about this
process at libvirt.org at all (?).
Final question: I have an old QEMU image. How to "import" it to virsh
script? Is there any easy way to do that?
Thanks,
Jun

I tried to run libvirtd to see if that fixes the problem, but got the
below error:
Yes, for QEMU you need to have the libvirtd daemon up & running. Before
attempting to connect with virt-install, make sure you can connect with
virsh, eg as a good test run:
virsh --connect qemu:///system capabilities
# libvirtd
libvir: QEMU error : internal error failed to set bridge forward delay to 0
Failed to autostart network 'default': internal error failed to set
bridge forward delay to 0
This suggests you are missing the 'brctl' command - it is part
of the bridge-utils packages

Then I believe this should be fixed: users should be able to run
libvirtd without brctl installed. I can still use QEMU/KVM before on
my machine without it, so I find no reason why it stop working now
with virt-install.
OK, now I install bridge-utils, and run libvirtd. After that, I tried
virt-install, but still got error like below:

There's nothing to fix - this is simply a deployment issue - the default
installation we provide sets up a 'default' virtual network which provides
guests with a NAT based network connection out of the box which requires
bridgeutils. If you don't want to use that then you can remove this default
config from /etc/libvirt/qemu/networks. All the QEMU network configs without
use of bridge-utils are pretty crap though, hence why we setup this default
networking config for people
OK, now I install bridge-utils, and run libvirtd. After that, I
tried
virt-install, but still got error like below:
How to fix this now?
Debug it with 'virsh' first to make sure the basic functionality is working
and then go onto virt-install.

Yes, virsh works well: it returns few pages of xml data.
However, "virt-install" still has problem like below. It seems to have
some thing with Xen? I dont install Xen on my machine.
Could you give some hints to fix this??

That command line has an error, you need to use --connect for the
URI, -c == --cdrom.

That command line has an error, you need to use --connect for the
URI, -c == --cdrom.
Yes, that was a mistake. I changed -c to --connect, and get the error
"Unsupported virtualization type" now. How can I fix it?

The current virt-install
release doesn't pick a useful default
for virtualization type: it is just hardcoded to use paravirt.
Since your host doesn't have paravirt capabilities it is
throwing an error. This is fixed upstream: we will default
to paravirt only if on a xen host, otherwise we use hvm.
You'll need to specify --hvm and --accelerate as cli params if
you want to install a kvm guest.
Also, use the --debug flag if you want to see more useful
output related specifically to what virt-install is doing.

Hmm, yeah we should check that and throw a more clear error message.
However, the root cause is that your capabilities xml is screwy
(posted a few messages back.) There is only a <domain> element
for x86_64 qemu but you're host arch is reported as i686.
What libvirt version are you using?
What virt-install/python-virtinst version are you using?
Is kvm installed?
What distro are you on?

That's perfectly valid. It merely means he's got the qemu-system-x86_64
binary installed on an i686 host. ie QEMU emulating x86_64 arch. Slow
as treacle.

Right, the caps xml isn't busted because there is a <guest>
element for the x86_64 emulator, it's busted because there
is _only_ a <domain> element for that emulator. AFAIK
every <guest> piece should have at least one <domain>
piece so that we know what domain type we can use that
emulator for, yet Jun's capabilities have all the qemu
emulators listed and only one <domain> element among
them.

What libvirt version are you using?

I use libvirt-0.4.4-cvs, and virt-install-0.300.3.
Is kvm installed?
Yes, but does that really matter? I guess
qemu is not even started at this step.
What distro are you on?
Ubuntu 8.04, gcc 4.2.3, python 2.5.2

Yes, but does that really matter? I guess qemu is not even started at
this step.
Yes it does matter because I am trying to figure out why your
capabilities xml is messed up.
Here is a piece of the capabilities xml you posted:
<guest>
<os_type>hvm</os_type>
<arch name='i686'>
<wordsize>32</wordsize>
<emulator>/usr/bin/qemu</emulator>
<machine>pc</machine>
<machine>isapc</machine>
</arch>
<features>
...
</features>
</guest>
This piece here should have a <domain> element, but since
it doesn't that means libvirt didn't have executable access
to /usr/bin/qemu. Is this named differently on Ubuntu? How
about all the other binaries (qemu-system-mips, ...)?
<guest>
<os_type>hvm</os_type>
<arch name='x86_64'>
<wordsize>64</wordsize>
<emulator>/usr/bin/qemu-system-x86_64</emulator>
<machine>pc</machine>
<machine>isapc</machine>
<domain type='qemu'>
</domain>
</arch>
<features>
...
</features>
</guest>
If kvm is installed, then this should have a kvm <domain>
entry. Is /dev/kvm present/kvm module loaded? Is
/usr/bin/qemu-kvm present?
Thanks,
Cole

Though I use Ubuntu, I installed KVM from source code. And the vanilla
QEMU is not installed. And I use the KVM binary for QEMU (so no
accelerator is active in that case)
And there is no /usr/bin/qemu, but only /usr/bin/qemu-system-x86_64 in
KVM installation.
<guest>
<os_type>hvm</os_type>
<arch name='x86_64'>
<wordsize>64</wordsize>
<emulator>/usr/bin/qemu-system-x86_64</emulator>

If kvm is installed, then this should have a kvm <domain>
entry. Is /dev/kvm present/kvm module loaded? Is
/usr/bin/qemu-kvm present?
There is nothing like qemu-kvm anywhere in my box. I guess that is
from Fedora package only? (I compiled and installed KVM from source
code)

I've been bitten by this very same error message in virt-install.
Took me absolutely ages to work out that I had to use the '--hvm'
option. It's a usability bug in virt-install, plain and simple.
Attached is a patch which clarifies the error message.
