I'm trying to learn xen. fc6 install, all updates except the kernel, which is 2.6.18-1.2869.fc6xen (the machine doesn't run the 2.6.19 kernel). If I log in as root, I get the following: I can run /usr/bin/virt-manager, but not /usr/sbin/virt-manager: # virt-manager Traceback (most recent call last): File "/usr/share/virt-manager/virt-manager.py", line 56, in ? import gtk ImportError: No module named gtk With xm I get: # xm Traceback (most recent call last): File "/usr/sbin/xm", line 8, in ? from xen.xm import main ImportError: No module named xen.xm # rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n"|fgrep xen kernel-xen-2.6.18-1.2869.fc6.i686 xen-devel-3.0.3-3.fc6.i386 xen-libs-3.0.3-3.fc6.i386 xen-3.0.3-3.fc6.i386 What am I missing?
