[SOLVED] Bad: unable to open connection to hypervisor URI 'qemu:///system'

tamhankarnikhil · 10-24-2013, 10:07 AM

Hello, I have a RHEL6 VM installed on VMware and trying to install another virtual machine inside VMware using virt-manager. Now, I have installed the virt-manager properly, but while creating a new VM, I am getting below error:

Quote:

unable to open connection to hypervisor URI 'qemu:///system':
unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: No such file or directory
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: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: No such file or directory

and below is the attached screenshot of the error displayed on virt-manager while creating a new VM

Here are the other details

[root@server ~]# rpm -qa libvirt
libvirt-0.8.1-27.el6.x86_64
[root@server ~]# rpm -qa virt-manager
virt-manager-0.8.4-8.el6.noarch
[root@server ~]# rpm -qa qemu-kvm
qemu-kvm-0.12.1.2-2.113.el6.x86_64
[root@server ~]# lsmod | grep qemu
[root@server ~]# rpm -qa libvirt-python
libvirt-python-0.8.1-27.el6.x86_64
[root@server ~]# service libvirtd status
libvirtd (pid 2381) is running...
[root@server ~]# ps ax | grep libvirtd
2381 ? Sl 0:03 libvirtd --daemon
29405 pts/1 S+ 0:00 grep libvirtd
[root@server ~]# ps ax | grep qemu
29422 pts/1 S+ 0:00 grep qemu

As you can see there is not output for "lsmod | grep qemu" and "ps ax | grep qemu" command.

Can anybody tell what is this issue and how to resolve it?

Did you read the error message?? I've bolded it above. Did you start libvirtd? Note the line in the message to verify that it's started...
Try starting the service before you try to use it:

Code:

service libvirtd start

Please see other details section in the question where I have mentioned that

[root@server ~]# service libvirtd status
libvirtd (pid 2381) is running...

Let me get this right. You have a vm running and within that vm you want to start another vm?

Anway, try qemu from command line. See what is says.

No. I have a windows host and a RHEL6 VM. I want another VM inside RHEL6 VM.

Right...which is EXACTLY what jefro said. Did you try running the command suggested?
