Slow I/O on NetBSD domU (on Debian dom0)
I have two Xen servers, the first one running Lenny (so Xen 3.2.1) and the
second one running Squeeze (Xen 4.0.1).
Both of them are running one or more Debian domUs without any particular issue.
NetBSD PV domUs, instead (tried with a freshly compiled netbsd-5), seem to
suffer from some I/O performance issues. Every time I start an intensive I/O
task (like "tar xjvf pkgsrc.tar.bz2"), the NetBSD domU starts to lag. ssh
connections take ages to be accepted, and generally every task and every
command seem to be very very slow. This doesn't happen on Linux and the other
domUs just run without any particular problem, they can also do intensive I/O
tasks without any problem.
I've also a NetBSD 5.1 Dom0 (Xen 3.3) with some NetBSD PV domUs and some Debian
Linux PV domUs. I cannot test it now, but I never noticed something like that.
