I only tested Gentoo guests though. But, I have Intel i7 cpu. This is an ~amd64 (unstable) host, running amd64 (stable) guests. The only clue is in messages: May 1 16:25:01 khamul kernel: [73366.634971] VBoxHeadless[2642]: segfault at 10 ip 00007fa35e40599f sp 00007fa35c5b8b00 error 4 in VBoxDD.so[7fa35e311000+144000] I downgraded virtual box from 4.1.14 to 4.1.12 and initial tests are good. A guest is doing a full emerge world and the first package is glibc. Previously it wouldn't even manage to download sources fully. It's too early to draw any real conclusions though. I'm still rather suspicious of glibc on the host (just as hunch, as that version seems to be popping up in many more bug reports than usual) -- Alan McKinnnon alan.mckin...@gmail.com
