Subject: [Bug 65081] Starting a second guest with -smp 2 makes the first guest very slow and the second one hang (or also very slow)

--- Comment #3 from Daniel Haid <d.haid@gogi.tv> ---
I removed all unnecessary arguments. The following command line is actually
sufficient to produce hanging guests:
qemu-system-x86_64 -enable-kvm -kernel vmlinuz-linux -initrd
initramfs-linux.img -append "console=ttyS0,57600" -nographic -smp 2
I tried to run multiple guests and found out the following: It is possible to
run multiple non-smp-guests (I tried three) and one smp-guest fine. But as soon
as a second smp-guest is started, both smp-guests hang. However, the
non-smp-guests are not affected!
