[GRASS-dev] Fwd: [SAC] OSGeo "tracsvn" VM down

[Nikos Alexandris]

@Martin,

was there recently a kernel update to the (Gentoo-)host? If yes, from my
minorest experience, it's not uncommon to have to ensure that the newer kernel
has been configured with support for specific modules (obviously,
related to KVM) or it is necesary to re-compile some modules (again,
obviously) related to KVM.
