35.9. Common Xen problems
When attempting to start the
xend
service, nothing happens. Type virsh list
and receive the following:
Error: Error connecting to xend: Connection refused. Is xend running?
Try to run
xend start
manually and receive more errors:
Error: Could not obtain handle on privileged command interfaces (2 = No such file or directory) Traceback (most recent call last:) File "/usr/sbin/xend/", line 33 in ? from xen.xend.server. import SrvDaemon File "/usr/lib/python2.4/site-packages/xen/xend/server/SrvDaemon.py" , line 26 in ? from xen.xend import XendDomain File "/usr//lib/python2.4/site-packages/xen/xend/XendDomain.py" , line 33, in ? from xen.xend import XendDomainInfo File "/usr/lib/python2.4/site-packages/xen/xend/image.py" , line37, in ? import images File "/usr/lib/python2.4/site-packages/xen/xend/image.py" , line30, in ? xc = xen.lowlevel.xc.xc () RuntimeError: (2, 'No such file or directory' )
What has most likely happened here is that you rebooted your host into a kernel that is not a
kernel-xen
kernel. To correct this, you must select the kernel-xen
kernel at boot time (or set the kernel-xen
kernel to the default in the grub.conf
file).
