This exactly is happening to me now. My host is a Debian Wheezy AMD64 running Qemu kvm 2.0.0+dfsg-4~bpo70+1 My guest is FreeBSD 10 FreeBSD 10.0-RELEASE (GENERIC) #0 r260789 And part way through make world via freebsd-wifi-build/build/bin/build I am experiencing spontaneous reboots. My kvm command line is: kvm --enable-kvm -localtime -m 1536 -smp 2 -k en-us -hda freebsd.qcow2 \ -soundhw sb16 -net nic -net user,hostfwd=tcp::62222-:22 -monitor stdio I built this VM and a build of world kernel install etc. completed without problems yesterday. But today when I repeated after a clean I am experiencing the problem. I am wondering whether having accidentally killed the guest corrupted to disk somehow, but the problem keeps happening even after running fsck on / > > With kind regards, > Matthew HTH, Andrew -- http://blog.oldcomputerjunk.net https://au.linkedin.com/in/amcdonnell https://github.com/andymc73 Twitter: @pastcompute GPG: http://www.andrewmcdonnell.net/gpg.html
