Sorry, I should have elaborated here. I don't think this is the correct fix because now libvirt.so has a dependency on xen libs, e.g. libxenstore, which (I think) defeats the purpose of modularizing the build. > I need to do some more testing with and > without modules, but wanted to raise this on the list for > comments/suggestions. > When building libvirt without driver modules, I'm not able to connect to the legacy xen driver # virsh version Compiled against library: libvirt 0.10.0 Using library: libvirt 0.10.0 Using API: QEMU 0.10.0 error: failed to get the hypervisor version error: internal error Cannot find suitable emulator for x86_64 # virsh -c xen:/// version error: internal error libxenlight state driver is not active error: failed to connect to the hypervisor Which is correct, since the libxl driver won't load if xend is active. But why is the legacy xen driver not tried? I can connect to the libxl one when xend is not active # virsh version Compiled against library: libvirt 0.10.0 Using library: libvirt 0.10.0 Using API: xenlight 0.10.0 Running hypervisor: xenlight 4.1.0 When building with driver modules and trying to connect to the legacy xen driver # virsh version Compiled against library: libvirt 0.10.0 Using library: libvirt 0.10.0 Using API: QEMU 0.10.0 error: failed to get the hypervisor version error: internal error Cannot find suitable emulator for x86_64 # virsh -c xen:/// version Compiled against library: libvirt 0.10.0 Using library: libvirt 0.10.0 Using API: Xen 0.10.0 Running hypervisor: Xen 4.1.0 So this is a change in behavior, where the connection must now be explicitly specified. Same goes for connecting to the libxl driver when built with driver modules # virsh version Compiled against library: libvirt 0.10.0 Using library: libvirt 0.10.0 Using API: QEMU 0.10.0 error: failed to get the hypervisor version error: internal error Cannot find suitable emulator for x86_64 # virsh -c xen:/// version Compiled against library: libvirt 0.10.0 Using library: libvirt 0.10.0 Using API: xenlight 0.10.0 Running hypervisor: xenlight 4.1.0 Suggestions on how to go about fixing all of this would be much appreciated :).
