=head1 DESCRIPTION
=head2 PPC (with HMC) specific:
The chvm command modifies the partition profile for the partitions specified in noderange. A partitions current profile can be read using lsvm, modified, and piped into the chvm command, or changed with the -p flag.
This command also supports to change specific partition attributes by specifying one or more "attribute equals value" pairs in command line directly, without whole partition profile.
=head2 PPC (using Direct FSP Management) specific:
chvm could be used to change the octant configuration values for generating LPARs. chvm is designed to set the Octant configure value to split the CPU and memory for partitions, and set Octant Memory interleaving value. The chvm will only set the pending attributes value. After chvm, the CEC needs to be rebooted manually for the pending values to be enabled. Before reboot the cec, the administrator can use chvm to change the partition plan. If the the partition needs I/O slots, the administrator should use chvm to assign the I/O slots.
chvm is also designed to assign the I/O slots to the new LPAR. Both the current IO owning lpar and the new IO owning lpar must be powered off before an IO assignment. Otherwise, if the I/O slot is belonged to an Lpar and the LPAR is power on, the command will return an error when trying to assign that slot to a different lpar.
The administrator should use lsvm to get the profile content, and then edit the content, and add the node name with ":" manually before the I/O which will be assigned to the node. And then the profile can be piped into the chvm command, or changed with the -p flag.
=head2 VMware/KVM specific:
The chvm command modifes the vm specified in noderange. Calling with deregister or purge options at the same time as the resize option is not recommended.
=head2 zVM specific:
The chvm command modifes the virtual machine's configuration specified in noderange.
=head1 OPTIONS
=head2 Common:
=over 10
=item B<-h>
Display usage message.
=item B<-v>
Command Version.
=back
=head2 PPC (with HMC) specific:
=over 10
=item B<-p> I<profile>
Name of an existing partition profile.
=item I<attr>=I<val>
Specifies one or more "attribute equals value" pairs, separated by spaces.
=item B<-V>
Verbose output.
=back
=head2 PPC (using Direct FSP Management) specific:
=over 10
=item B<-i>
Starting numeric id of the newly created partitions. For Power 775 using Direct FSP Management, the id value only could be B<1>, B<5>, B<9>, B<13>, B<17>, B<21>, B<25> and B<29>.
=item B<-m>
memory interleaving. The setting value only could be B<1> or B<2>. B<2> means B<non-interleaved> mode (also 2MC mode), the memory cannot be shared across the processors in an octant. B<1> means B<interleaved> mode (also 8MC mode) , the memory can be shared. The default value is B<1> .
=item B<-r>
partition rule.
If all the octants configuration value are same in one CEC, it will be " B<-r> B<0-7>:I<value>" .
If the octants use the different configuration value in one cec, it will be "B<-r> B<0>:I<value1>,B<1>:I<value2>,...B<7>:I<value7>", or "B<-r> B<0>:I<value1>,B<1-7>:I<value2>" and so on.
The octants configuration value for one Octant could be B<1>, B<2>, B<3>, B<4>, B<5>. The meanings of the octants configuration value are as following:
1 -- 1 partition with all cpus and memory of the octant
2 -- 2 partitions with a 50/50 split of cpus and memory
3 -- 3 partitions with a 25/25/50 split of cpus and memory
4 -- 4 partitions with a 25/25/25/25 split of cpus and memory
5 -- 2 partitions with a 25/75 split of cpus and memory
=item B<-p> I<profile>
Name of I/O slots assignment profile.
=item B<lparname>={B<*>|B<name>}
Set LPAR name for the specified lpars. If '*' specified, it means to get names from xCAT database and then set them for the specified lpars. If a string is specified, it only supports single node and the string will be set for the specified lpar. The user can use lsvm to check the lparnames for lpars.
