I'm also having this problem but with Linux 2.6.32.2 + qemu-kvm-0.12.1.1
in the host:
Jan 9 16:11:11 ubuntu kernel: [758479.480219] qemu-system-x86[29330]:
segfault at 90 ip 00007f5816bf3990 sp 00007fff9258fc88 error 4 in
libpthread-2.7.so[7f5816be8000+16000]
I've guest with one cpu in which I try to add one more. For this I
execute the following in qemu monitor and here it is where I got
segmentation fault:
(qemu) cpu_set 1 online
Connection closed by foreign host.
I'm not sure if the procedure that I'm following is the correct one. I
tried as much without using additional parameters when boots guest like
using -smp 1,maxcpus=2, but I reach the same result.
The Kernel of guest has checked the "Support for hot-pluggable CPUs"
option, in case it is necessary.
Regards,
Daniel
