[Solved] Cannot install KVM guest on CentOS/RedHat

UNIX for Advanced & Expert Users
1

Hi,

I've a CentOS Server and I need to create KVM guest machine without X.

 /usr/sbin/virt-install --name server1 --ram 4000 --vcpus=8  --file=/srv/virtual/server1.img --file-size=20 --cdrom /tmp/server1.iso --mac=52:54:00:fd:48:7c

The iso was created with cobbler...
So, now the machine is present :

root@mainserver:/etc/libvirt/qemu $ virsh list 
 Id Name                 State
----------------------------------
  5 server1          running

But the installation was not completed, so I couldn't stop it! I couldn't connect it! and when I try to install again:

What should I do?

Please help!

According to the manual page, you should use virsh to "undefine" server1 before running virt-install.

Thank you! I can restart the installation...

After the ok, it start a black screen with "_" and hangs...! What could be the problem?

I don't have that specific ISO to test with, but the command you're using works fine with another one I have.

Did you create it, or download it (and where from)?

It was created with our cobbler system and I've copied into my server

I've seen the following error in logs:

kernel: kvm: 27302: cpu0 unimplemented perfctr wrmsr: 0xc1 data 0xabcd

I've seen a bug on Google but I don't the os version is not to old....

I've find the solutions :

I must to add --vnc in my command, than start a vncviewer on the server through ssh -x server.

Thanks for your
