Hi all,
I am trying to use virt-install to install domU image. However, I
encountered the following issue. It seems that a connection driver is
needed for Xen.
I am new to both libvirt and Xen. Anyone have any ideas on what's wrong
with the following error ?
# virt-install --connect=xen:/// -p -d

By the way, Xen is installed successfully as both "xm list" and "xm
info"
can output appropriately.
Thanks,

This probably means that your copy of libvirt.so and libvirtd was built
without xen support. What does
virsh --version=long
say? Also, are you sure libvirtd is running?

Eric,
Here is the output:
# virsh --version=long
Virsh command line tool of libvirt 0.9.10
See web site at http://libvirt.org/
Compiled with support for:
Hypervisors: Xen QEmu/KVM UML OpenVZ VirtualBox LXC Test
Networking: Remote Daemon Network Bridging Nwfilter VirtualPort
Storage: Dir Filesystem SCSI Multipath iSCSI LVM
Miscellaneous: SELinux Secrets Debug
It seems that it does support Xen.
I am not sure if libvirtd is running so I use the following command to
start it:
[root@XenTester srv]# /etc/rc.d/init.d/libvirtd start
But the same error is still there.
Am I using the right way to start libvirtd service? Are there any other
possible reasons of this error?
Thanks,

This probably means that your copy of libvirt.so and libvirtd was

without xen support. What does

say? Also, are you sure libvirtd is running?
In addition, I want to know your libvirt.so, libvirtd, xend location,
for example,
# which libvirtd
# which xend
# locate libvirt.so
Please also make sure xend service is running:
# service xend status

Yeah, Xen indeed appears in Hypervisors line.

Right, you may also use

libvirtd status or ps -ef|grep libvirtd.
But the same error is still there.

Alex,
Here is some information:
# /etc/init.d/xencommons start
Starting xenstored...
Setting domain 0 name...
Starting xenconsoled...
[root@XenTester su]# /etc/init.d/xend start
[root@XenTester su]# which libvirtd
/usr/local/sbin/libvirtd
[root@XenTester su]# which xend
/usr/sbin/xend
[root@XenTester su]# locate libvirt.so
/usr/lib64/libvirt.so.0
/usr/lib64/libvirt.so.0.9.4
/usr/local/lib/libvirt.so
/usr/local/lib/libvirt.so.0
/usr/local/lib/libvirt.so.0.9.10
You have 2 different libvirt versions 0.9.4 and
0.9.10, and your 0.9.10
is put under the
/usr/local/lib directory, so I guess you haven't used ./configure with
--prefix=/usr option
or directly use ./autogen.sh --system when you configure and compile
libvirt.
And also please yum install strace -y if you haven't installed strace
rpm, then run the following operation:
# strace -o strace.txt virt-install --connect=xen:/// -p
Then attach strace.txt as a attachment.
Thanks,
Alex
