This probably means that your copy of
libvirt.so and libvirtd was built<br>
without xen support. What does<br>
<br>
virsh --version=long<br>
<br>
say? Also, are you sure libvirtd is
running?<br>
</blockquote>
</div>
</blockquote>
</div>
In addition, I want to know your libvirt.so,
libvirtd, xend location, for example,<br>
# which libvirtd<br>
# which xend<br>
# locate libvirt.so<br>
<br>
Please also make sure xend service is running:<br>
# service xend status <br>

Yeah, Xen indeed appears in Hypervisors line.

I am not sure if libvirtd is running so I

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.<br>
<br>
Am I using the right way to start libvirtd
service? Are there any other possible

You have 2 different libvirt versions 0.9.4 and 0.9.10, and
your 0.9.10 is put under the<br>
/usr/local/lib directory, so I guess you haven't used
./configure with --prefix=/usr option<br>
or directly use ./autogen.sh --system when you configure and
compile libvirt.<br>
<br>
And also please yum install strace -y if you haven't
installed strace rpm, then run the following operation:<br>
<br>
# strace -o strace.txt virt-install --connect=xen:/// -p<br>
<br>
Then attach strace.txt as a attachment.<br>
<br>
Thanks,<br>

Alex,<br>
<br>
Thanks. I have run ./autogen.sh --system. And "make" and "make
install" the libvirt once again.<br>
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:<br>
<br>
/usr/bin/install: cannot stat `./api.html': No such file or
directory<br>
/usr/bin/install: cannot stat `./api_extension.html': No such

It's not important for our issues.<div><br>

Do you think this type of errors will affect the functionality
of libvirt?<br>
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".<br>
Please find strace.txt attached.<br>
</div>
</div>
</blockquote></div>
I saw virt-install is opening /usr/lib64/libvirt.so.0 in strace.txt:
<pre>open("/usr/lib64/libvirt.so.0", O_RDONLY) = 7
</pre>
I want to confirm whether you're using compiling libvirt 0.9.10, <br>
ll /usr/lib64/libvirt.so.0 say what?<br>
