Re: [Xen-devel] vmx problem

Hi,

I believe your /dev/sda1 is /boot. It appears all your available space on harddisk /dev/sda is used up (all 53309 cylinders). Could you free up disk space by deleting some partitions (be sure to backup your data first!!!)? Or do you have another empty harddisk?

Having another empty harddisk is a better idea. When you plug it in, it will become /dev/sdb (if SCSI or SATA).

Disk /dev/sda: 438.4 GB, 438489317376 bytes
255 heads, 63 sectors/track, 53309 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

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..
