Hi

I am not using virt-manager or any management solutions.

I created my virtual machines manually.
You mean using pre-built guest images?
For virtual disks, you can create it using dd or use LVM or physical partitions.
Please guide me creating LVMs. blow is my partition details:
 [root@Server1-FC11 ~]# fdisk -l
Disk /dev/sda: 438.4 GB, 438489317376 bytes
255 heads, 63 sectors/track, 53309 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000080

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1          13      104391   83  Linux
/dev/sda2              14        2180    17406427+  82  Linux swap / Solaris
/dev/sda3            2181       42776   326087370   83  Linux
/dev/sda4           42777       53309    84606322+   5  Extended
/dev/sda5   *       42777       53309    84606291   83  Linux

After that you just need to create a vm configuration file. Then you start the vm using the xm create command.

Yeah... I believe so till now. If this is true why my virt-manager behaving like this. PFA some screen shots of virt-manager, both virt types para and fully are disabled. and it stops me from creating a VM.

For paravirtualized guests I don't think you need the hardware virtualization assist (VMX). You only need vmx when you want to create HVM guests.

No i just need to enable virtualization flag on my intel xeon quad core processor, so that i can create paravirt VMs in my set-up. Which at this time virt-manager is not allowing me to do.

Any plans for 'nested' VMX support? KVM seems to have that..
