I am facing one issue in XEN 64 bit kernel. Description: After installation of guest OS I am unable to start the guest. Even "virsh#list --all" unable to list my inactive domains. I am using 2.6.18 kernel (64 Bit). I have used Fedora core 6 32 bit version. In that I could install Solaris as a guest apart from all other Linux Distro. Please suggest me the right solution.
