https://bugzilla.kernel.org/show_bug.cgi?id=65081 --- Comment #3 from Daniel Haid <d.haid@xxxxxxx> --- 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! -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
