Set Up the Management Node for KVM¶
Set Up the kvm storage directory on the management node(optional)¶
It is a recommended configuration to create a shared file system for virtual machines hosting. The shared file system, usually on a SAN, NAS or GPFS, is shared among KVM hypervisors, which simplifies VM migration from one hypervisor to another with xCAT.
The easiest shared file system is
/install directory on the management node, it can be shared among hypervisors via NFS. Please refer to the following steps :
Create a directory to store the virtual disk filesmkdir -p /install/vms
export the storage directoryecho "/install/vms *(rw,no_root_squash,sync,fsid=0)" >> /etc/exports exportfs -r
Note: make sure the root permission is turned on for nfs clients (i.e. use the
no_root_squash option). Otherwise, the virtual disk file can not work.
