Hello, I just installed a fresh CentOS 7 minimal version on my server 
(dell r610).

Linux testServer 3.10.0-229.1.2.el7.x86_64 #1 SMP Fri Mar 27 03:04:26 
UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

then made update and installed kvm tools

yum -y install qemu-kvm qemu-img libvirt virt-install 
libvirt-daemon-driver-* /
/Name        : qemu-kvm
Arch        : x86_64
Epoch       : 10
Version     : 1.5.3
Release     : 86.el7_1.1/
/Name        : virt-install
Arch        : noarch
Version     : 1.1.0
Release     : 12.el7

And then I got an error when I'm using the virt-install command with 
"--cpu host" option:

  virt-install --connect qemu:///system -n archlinux -r 1024 *--cpu 
host* --vcpus=1 --disk path=archlinux.raw,bus=virtio --cdrom 
archlinux-2015.02.01-dual.iso --os-type linux --network 
bridge:virbr0,model=virtio --hvm --graphics vnc,listen=

Starting install...
*ERROR    unsupported configuration: host doesn't support invariant TSC*
Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
   virsh --connect qemu:///system start archlinux
otherwise, please restart your installation.

I've double check the Virtualization option in the BIOS is enabled.

Here is a summary of /proc/cpuinfo:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 26

Am I missing something ? I'd like to know if there is a way to fix this.

If you need more informations, just ask.

Thank you for your time and consideration in this matter.
