Alex,
I changed the symbolic link to "/usr/local/lib/libvirt.so.0.9.10".
Here is the running script:
[root@XenTester libvirt-0.9.10]# rm /usr/lib64/libvirt.so.0
rm: remove symbolic link `/usr/lib64/libvirt.so.0'? yes
[root@XenTester libvirt-0.9.10]# ln -s
/usr/local/lib/libvirt.so.0.9.10 /usr/lib64/libvirt.so.0
It's not enough, you had better to clean up your dirty libvirt
environment, for example, remove all of
libvirt rpm package on host, then recompile libvirt and ./configure
--prefix=/usr && make && make install, or ./autogen --system && make &&
make install.
I run "strace -o strace.txt virt-install --connect=xen:/// -p" once
again, and the following error came out:
ERROR Error in network device parameters: Virtual network 'default'
does not exist: this function is not supported by the connection
driver: virNetworkLookupByName
the strace.txt is attached.
I think current xen URI works well for you, and you may try virt-install
--connect=xen:/// -p -d or virt-install -p -d to confirm this.
The above error is another issues, you need to change others stuff, it's
not enough to just link
/usr/local/lib/libvirt.so.0.9.10 /usr/lib64/libvirt.so.0, please follow
answer 1.
Are there any other places I need to change in order to let the system
know I am running libvirt.so.0.9.10?
Thanks,

So you meant that I used a wrong libvirt.so? How can I correct this?

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?
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

Libvirt virtualization library http://libvirt.org
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.
Yeah, Xen indeed appears in Hypervisors line.
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
Right, you may also use service libvirtd start, and
check it by service libvirtd status or ps -ef|grep
libvirtd.
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,

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

[root@XenTester su]# which xend
/usr/sbin/xend
[root@XenTester su]# locate libvirt.so

/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
Alex,
Thanks. I have run ./autogen.sh --system. And "make" and
"make install" the libvirt once again.
I encountered one type of errors while running "make
install", it seems that the installer is looking for a bunch
of HTML files under /usr/bin/install. here is the error info:
/usr/bin/install: cannot stat `./api.html': No such file or
directory
/usr/bin/install: cannot stat `./api_extension.html': No such
file or directory
/usr/bin/install: cannot stat `./apps.html': No such file or
directory
/usr/bin/install: cannot stat `./archdomain.html': No such
file or directory
/usr/bin/install: cannot stat `./architecture.html': No such
file or directory
/usr/bin/install: cannot stat `./archnetwork.html': No such
file or directory
/usr/bin/install: cannot stat `./archnode.html': No such file
or directory
(there are still tens of HTML files missing)
....
It's not important for our issues.
Do you think this type of errors will affect the
functionality of libvirt?
Also, I checked and it seems that I've the latest strace
package installed. So I run "strace -o strace.txt
virt-install --connect=xen:/// -p".
Please find strace.txt attached.
I saw virt-install is opening /usr/lib64/libvirt.so.0 in
strace.txt:
open("/usr/lib64/libvirt.so.0", O_RDONLY) = 7
I want to confirm whether you're using compiling libvirt 0.9.10,
ll /usr/lib64/libvirt.so.0 say what?
Thanks,
Alex
Thanks,
[root@XenTester su]# service xend status
[root@XenTester su]# ps -ef|grep libvirtd
root 2242 1 0 21:52 ? 00:00:00 libvirtd
--daemon
root 3295 3112 0 21:59 pts/0 00:00:00 grep

Can you see if it is normal here?
Thanks,
