You can configure a virtual machine to have up to eight virtual processors or CPUs. The number of licensed
CPUs on the host and the number of processors supported by the guest operating system limit the number of
virtual processors that you can create.

VMware Virtual SMP is required to power on multiprocessor virtual machines. The Virtual CPUs page appears
for multiprocessor hosts.

Quote:
Procedure

1 On the CPUs page of the New Virtual Machine wizard, select the number of virtual processors from the
drop-down menu.
2 Click Next.

But when i install the rpm, what is the difference between RPM -i and RPM -u?

When i do a RMP -u is it installed next to the old kernel?

Hi,

sudo rpm -ivh {rpm-file} Install the package

i-install
v-verbose
h-print hashes

sudo rpm -Uvh {rpm-file} Upgrade package

U-upgrade

But its better to use ivh even for update
