Remus Toolkit Differences

Remus in XL

Xen 4.5 and newer

In 4.5 the XM toolstack is not supported any more. Remus is invoked via the "xl remus ..." syntax. This syntax can be found in recent xl man pages (search for the "remus" option).

Xen 4.4.

Xenlight is the current toolkit for Xen Project. In xenlight, Remus is invoked via the "xl remus ..." syntax. This syntax can be found in recent xl man pages (search for the "remus" option).

As of 4.4, Remus support in xl is still in experimental (proof-of-concept) phase. Per the man page, there is no support for network or disk buffering in the current release.

Remus in XM

Remus was originally implemented when Xen Project was using the xm toolkit. If you are still using xm, you will need to use the "remus" command to control the software.

The "remus" command uses the following syntax:

Usage: remus [options] domain [destination]

Options:
 -h, --help            show this help message and exit
 -i MS, --interval=MS  checkpoint every MS milliseconds
 -p PORT, --port=PORT  send stream to port PORT
 --blackhole           replicate to /dev/null (no disk checkpoints, only
                       memory & net buffering)
 --no-net              run without net buffering (benchmark option)
 --no-compression      run without checkpoint compression
 --timer               force pause at checkpoint interval (experimental)
