Your VNC is failing as the VM is not running, did you enable hardware virtualization in your BIOS? Looking at your log it seems the VM fails to start due to KVM virtualization error.

Ii have installed proxmox on hp proliant server,sorry my ignorance what is KVM virtualization error.

Your CPU(s) need to support hardware virtualization in order for KVM to work properly. You can check if your CPU(s) support this using:

To check if your CPU is virtualization compatible, check for the vmx or svm tag in this command output: egrep '(vmx|svm)' /proc/cpuinfo

You can also go to your VM and click on the options menu and then set KVM Hardware virtualization to off and see if the machine boots. If it does then you have not enabled hardware virtualization in the BIOS or your CPU(s) do not support it.

I have done both of those options, i have enabled the Intel VT feature in the BIOS and turned off KVM Hardware virtualization on VM again same error.
my pc is HP ProLiant DL360 Generation 5

Have you tried starting it with hardware virtualization on now that it is enabled in the bios?

i don`t know if `im allowed to post a link here but this one helped me to solve the problem for : Intel Virtualization Technology
