I'm try to debug (disable-strip), but i'm start vps from libvirt (i'm
add -s flag to qemu, to start gdb), but when i'm attach to remote
session,qemu aready dies, or all works fine.
does it possible to determine by this dmesg what happening in qemu
binary with debug symbols?
qemu-system-x86[34046]: segfault at 401364 ip 00007f33f52a1ff8 sp
00007f3401ecad30 error 4 in qemu-system-x86_64[7f33f4efd000+518000]
