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?
