Xen 4.0
Hi!
Xen -unstable entered feature freeze state in favour to a
stable Xen 4.0.
NetBSD specific changes:
- xenbackendd is upstream and is launched by xend
- build system improved to reduce number of patches
to build on NetBSD
Pending patches:
- There are patches for Balloon support written
by Cherry and Joerg Sonnenberger but haven't got
any patches I can submit upstream.
If the changes are not that intrusive they can
still go upstream for Xen 4.0.
New Xen features:
- Xen supports up to 128 virtual cpus for DomUs
(both HVM and PV)
- Xen supports page-offlining, physical CPU hotplugging,
physical memory hotplugging.
- Xen NUMA support is on by default now. It is no longer
necessary to add 'numa=on'
- Xen machine check has been improved to disable memory
and physical CPUs in error. Dom0 gets notified when this
happens.
- There can be multiple Xen installations side by
side in different install directories.
- Simplified guest config for HVM guests:
The path to hvmloader and qemu-dm are optional
and no longer mandatory.
