[CentOS] Virtual Machine Manager error

wild guess (as I haven't yet played with el6 virtalization)

# yum install qemu-kvm qemu-kvm-tools qemu-img

Hi,

I am getting the exact same error on a CentOS 6.2 X86_64 machine that I have
just setup.

Removed and re-installed ALL the *virt* and *qemu* packages ( re-installed from
the distro CD ).

The machine is a DELL Optiplex 755 with an Intel x86_64 processor.


I found there was a similar bug on Fedora a while ago and it was fixed here:

https://bugzilla.redhat.com/show_bug.cgi?idr6167


Not sure if the two are related but it seems likely given the descriptions...

Regards,
D

My CentOS 6.2 x86_64 KVM system works as expected.

By I have not updated libvirt, libvirt-client and libvirt-python! :

Try downgrading those 3 packages.

The error that you are reporting is simply telling you that the libvirtd
daemon is not running. You can confirm this with

ps auxw | grep libvirtd

root 3329 0.0 0.0 600440 8420 ? Sl 10:22 0:00
libvirtd --daemon

If it is not running then attempt to start it with:
service libvirtd start

To have it start at system startup run
chkconfig libvirtd on

I have one system where, for some reason 'service libvirtd start' fails,
but running

/etc/init.d/libvirtd start

works. I have not had a chance to determine why yet. Also, if libvirtd
fails to start, check your log files /var/log/messages /var/log/boot.log
/var/log/audit/audit.log for errors. You could also try temporarily
disabling selinux enforcement with "setenforce 0". Use 'setenforce 1'
to renable it.

Greetings,
No joy.

Greetings,
I double checked this issue. Intel virtualization is enabled in BIOS.

BTW is there any command in Centos to check the current BIOS settings?
I have in mind commands like lspci, dmidecode, ethtool, mii-tools etc
in case of hardware when I am asking this question.

TIA

service libvertd start


libvertd meaning the libvert daemon.

you might have more luck with


service libvirtd status
