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> main() File "/usr/bin/virt-install", line 345, in main conn = cli.getConnection(options.connect) File "/usr/lib/python2.5/site-packages/virtinst/cli.py", line 92, in getConnection return libvirt.open(connect) 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???
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
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.
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??
Thanks, J
# LIBVIRT_DEBUG=1 virt-install -c qemu:///system --name jeos2 --ram 500 --file img.jeos2 --cdrom jeos-8.04.1-jeos-i386.iso
That command line has an error, you need to use --connect for the URI, -c == --cdrom. - Cole
