hi,
I''m sorry to bother you again.
I install xen 4.1.2 on the CentOS 6.0 with linux kernel 3.0.4 as the domain0
kernel.Then I would like to start a paravirtualized guest os.After several
attempts to write a configure file for paravirtualized guest os ,i failed in the
procedure of "xm create centos.cfg"
The following is the content of my file "centos.cfg"
1 name = "centos-pv"
2 memory = "1024"
3 disk = [ ''tap2:aio:/home/vm/pvm/centos/vmdisk.img,xvda,w'',
]
4 root = "/dev/xvda ro"
5 vif = [ ''bridge=eth0'', ]
6 vcpus=1
7 on_reboot = ''restart''
8 on_crash = ''destroy''
9 on_poweroff = "destroy"
when I create it ,the error blow happened.
[root@localhost centos]# xm create vmdisk.cfg
Using config file "./vmdisk.cfg".
Error: (''create'',
''-aaio:/home/vm/pvm/centos/vmdisk.img'') failed (55808 blktap
kernel module not installed )
So i turn to use virt-manager to start a pvm,but this try is also not well.
when I set up virt-manager on the command line ,a window pop up which show the
following error:
Unable to open a connection to the Xen hypervisor/daemon.
Verify that:
- A Xen host kernel was booted
- The Xen service has been started
Details:
Unable to open connection to hypervisor URI ''xen:///'':
no connection driver available for xen:///
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/connection.py", line 992,
in _try_open
None], flags)
File "/usr/lib64/python2.6/site-packages/libvirt.py", line 111, in
openAuth
if ret is None:raise libvirtError(''virConnectOpenAuth()
failed'')
libvirtError: no connection driver available for xen:///
I confirm that in the file "xend-config.sxp"
(xend-http-server yes) and (xend-unix-server yes) are uncommented.
Now I don''t know what to do next.Please help!
