https://bugzilla.kernel.org/show_bug.cgi?id=65081 --- Comment #3 from Daniel Haid d.h...@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! -- 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 majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Some more information about the bug: Instead of two -smp 2 guests, one -smp 3 (or higher) guest will also hang. And note that when running the two guests, they are running as different users. How can they ever be allowed to influence each other? -- 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 majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

https://bugzilla.kernel.org/show_bug.cgi?id=65081 --- Comment #1 from Daniel Haid d.h...@gogi.tv --- I have been told that I should provide the command line I am using, so here it is: qemu-system-x86_64 -enable-kvm -kernel vmlinuz-linux -initrd initramfs-linux.img -append console=ttyS0,57600 loglevel=7 root=/dev/vda rw -nographic -m 512 -drive file=/dev/mapper/vg0---root,if=virtio -drive file=/dev/mapper/vg0---swap,if=virtio -net nic,model=virtio -net tap,name=tap0,ifname=tap0,script=no,downscript=no -smp 2 The is different for the two guests. -- 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 majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
