11.6.2 VM aborts with out of memor y errors on Solaris 10 hosts

Solaris 10 hosts (bug 1225025) requires swap space equal to, or greater than the host’s

physical memory size. For example, 8 GB physical memory would require at least 8 GB

swap. This can be conﬁgured during a Solaris 10 install by choosing a ’custom install’

and changing the default partitions.

For existing Solaris 10 installs, an additional swap image needs to be mounted and

used as swap. Hence if you have 1 GB swap and 8 GB of physical memory, you require

to add 7 GB more swap. This can be done as follows:

For ZFS (as root user):

zfs create -V 8gb /_<ZFS volume>_/swap

swap -a /dev/zvol/dsk/_<ZFS volume>_/swap

To mount if after reboot, add the following line to /etc/vfstab:

/dev/zvol/dsk/_<ZFS volume>_/swap - - swap - no -

Alternatively, you could grow the existing swap using:

zfs set volsize=8G rpool/swap

And reboot the system for the changes to take effect.

For UFS (as root user):

mkfile 7g /path/to/swapfile.img

swap -a /path/to/swapfile.img

To mount it after reboot, add the following line to /etc/vfstab:

/path/to/swap.img - - swap - no -
