Remus provides fault tolerance for virtual machines by sending continuous
|
|
checkpoints to a backup, which will activate if the target VM fails.
|
|
|
|
See the website at https://wiki.xen.org/wiki/Remus for details.
|
|
|
|
Using Remus with libxl on Xen 4.5 and higher:
|
|
To enable network buffering, you need libnl 3.2.8
|
|
or higher along with the development headers and command line utilities.
|
|
If your distro does not have the appropriate libnl3 version, you can find
|
|
the latest source tarball of libnl3 at http://www.carisma.slowglass.com/~tgr/libnl/
|
|
|
|
Disk replication:
|
|
VMs protected by Remus need to use DRBD based disk backends. Specifically, you
|
|
need a compile and install a custom version of DRBD, that is available publicly
|
|
at https://github.com/rshriram/remus-drbd
|
|
This code is based on DRBD 8.3.11 and uses a new replication protocol (named
|
|
protocol D) for asynchronous disk checkpoint replication. A protected VM's DRBD
|
|
disks on the primary and backup hosts need to be configured to use protocol D
|
|
as the replication protocol. An example resource configuration file can be found
|
|
in the aforementioned github repository.
