6.73 (x86 Only) Solaris 11 Guest With More Than 2 VCPUs Hangs at Boot

When booting a virtual machine with running Oracle Solaris 11 and configured with more than 2 virtual CPUs, the guest OS hangs. This may be caused by a Solaris bug related to a change in the Xen hypervisor.

Workaround: To make Solaris 11 run on Oracle VM 3.3 with more than 2 virtual CPUs, perform the following steps to implement a manual fix:

During the installation or first time boot up, edit the grub menu and append the -kd kernel boot parameter.
Continue with the boot to run the Solaris kmdb. When the following screen prompt is displayed:
```
Welcome to kmdb 
[0]> 
```
Enter the command:
```
cmi_no_init/W 1
```
Enter the following to continue the installation or system boot:
```
:c
```
After Solaris is installed and booted up, append the following line to the /etc/system file to make this change persistent across system reboot.
```
set cmi_no_init = 1
```
