Re: KVM guest does not start - 100% CPU

Next update

I was able to boot in rescue mode and install grub.
Noticed that /boot/grub2/grub.cfg is empty and recreated it.

Direct boot did not work.

Only way I was ablr to get it work is to boot in anaconda and quit install.

Not ideal, but will do the job until fix is discovered.

Re: Network installation fails (Closest mirror)

As already mentioned entering URL works.

If you choose closest mirror option it does not.

Network installation fails (Closest mirror)

When I use default option closest mirror installation cannot download metadata (probably wrong URL).
Is that a bug in the installer?

Setting up URL manually (http option) works.

Re: OS problem?

It might be that hardware is too new for CentOS 6.
On Dell site I see it supports CentOS 7.

Give it a try.

You might need to add drivers in case 80G drive is on unsupported controller.

Please, provide information about the hardware.
