The following notes show the precautions to be observed for adding a virtual disk.
Specify "virtio" as the bus type and create a virtual disk as a VirtIO device.
If you use Virtual Machine Manager to create the virtual disk, select "Virtio Disk" as the device type.
Virtual IDE disks (bus type "IDE") are not supported.
Set the size of the host disk (logical unit of ETERNUS Disk storage system) to less than 2 TB.
As a consequence of this setting, the disk size of the guest will also be less than 2 TB.
As the disk area on the host side, you can specify the device names below:
Device names generated by the Linux udev facility (udev device names)
Example: /dev/disk/by-id/xxxxxxxx (for a disk)
Example: /dev/disk/by-id/xxxxxxxx-part1 (for a partition)
SDX object names of PRIMECLUSTER GDS
Example: /dev/sfdsk/class0001/dsk/volume0001
If you are using an SDX object of PRIMECLUSTER GDS, you can only use a volume in a single configuration.
Non-single configuration volumes (mirrored volumes, striped volumes, concatenation volumes, or volumes consisting of tiered disk groups) cannot be used.
Allocate a disk or partition of the host to the guest.
Figure F.3 Allocating a disk of the host to the guest
Figure F.4 Allocating a partition of the host to the guest
If you allocate partitions of the host to the guest, do not connect multiple partitions on the same disk to the same guest.
Figure F.5 Connecting multiple partitions on the same disk to different guests (OK)
Figure F.6 Connecting multiple partitions on the same disk to the same guest (Bad)
