[libvirt-users] No qemu-dm process for running domain

Hi, My C application is using libvirt to operate domains, but I found when I started a domain with my application, there was no qemu-dm for this running VM, and I can not access this domain with the graphic console provided by virt-manager. But if I started the same domain with virsh which linked with the libvirt shipped in OS, everything was OK, there will be a qemu-dm process for the running domain, and the graphic console provided by virt-manager worked well. The libvirt used by my application is libvirt-0.6.4, I just downloaded libvirt-0.6.4.tar.gz from http://libvirt.org/sources/old/libvirt-0.6.4.tar.gz, and I built it by running "./configure --prefix=/usr && make". Here are the details of my machine: # cat /etc/redhat-release Scientific Linux SL release 5.4 (Boron) # uname -an Linux ib06b07 2.6.18-164.11.1.el5xen #1 SMP Wed Jan 20 08:53:10 EST 2010 i686 i686 i386 GNU/Linux Was there anything wrong when I built libvirt-0.6.4? Should I enable some compilation options for launching qemu-dm process for running domains? Any suggestions will be really appreciated, thanks in advance! Regards, Qian
