chvm could be used to modify the resources assigned to partitions. The admin shall specify the attributes with options \ *vmcpus*\ , \ *vmmemory*\ , \ *add_physlots*\ , \ *vmothersetting*\ , \ *add_vmnics*\ and/or \ *add_vmstorage*\ . If nothing specified, nothing will be returned.

====================
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.

\ **--cpupin hostcpuset**\
To pin guest domain virtual CPUs to physical host CPUs specified with \ *hostcpuset*\ .
\ *hostcpuset*\ is a list of physical CPU numbers. Its syntax is a comma separated list and a special
markup using '-' and '^' (ex. '0-4', '0-3,^2') can also be allowed. The '-' denotes the range and
the '^' denotes exclusive.
Note: The expression is sequentially evaluated, so "0-15,^8" is identical to "9-14,0-7,15" but not
identical to "^8,0-15".
\ **--membind numanodeset**\
It is possible to restrict a guest to allocate memory from the specified set of NUMA nodes \ *numanodeset*\ .
If the guest vCPUs are also pinned to a set of cores located on that same set of NUMA nodes, memory
access is local and improves memory access performance.
\ **--devpassthru pcidevice1,pcidevice2...**\
The PCI passthrough gives a guest VM direct access to I/O devices \ *pcidevice1,pcidevice2...*\ .
The PCI devices are assigned to a virtual machine, and the virtual machine can use this I/O exclusively.
The devices list are a list of comma separated PCI device names delimited with comma, the PCI device names can be obtained by running \ **virsh nodedev-list**\ on the host.
