[libvirt-users] libvirt on Raspberry Pi, block by parameter "-S"

[Xu Ding]

Hi

I have used libvirt on Raspberry Pi Debian.
I can start the vm,  but it just starts and doesn't continue.
I find the qemu-system-arm command generated by virsh has a parameter "-S", when I copy the command, remove the parameter,  run it in the console, the vm can run normally.
But I don't know how to remove  the parameter in the xml file, or in virsh.

Regards

Thank you

Here's the qemu-system-arm command, generated by libvirt:

LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/local/bin/qemu-system-arm -name test -S -machine vexpress-a15,accel=kvm,usb=off -cpu host -m 500 -realtime mlock=off -smp 1,sockets=1,cores=1,threads=1 -uuid cab134ea-eed8-42e7-88cb-403ee2801e22 -nographic -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/test.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -boot menu=off,strict=on -kernel /home/pi/src/vexpress-zImage -append "root=/dev/vda rw console=ttyAMA0" -dtb /home/pi/src/vexpress-v2p-ca15-tc1.dtb -usb -drive file=/home/pi/src/test.qcow2,if=none,id=drive-virtio-disk0,format=qcow2 -device virtio-blk-device,scsi=off,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -drive file=/home/pi/src/opensuse.img,if=none,media=cdrom,id=drive-virtio-disk1,readonly=on,format=raw -device virtio-blk-device,scsi=off,drive=drive-virtio-disk1,id=virtio-disk1 -net nic,macaddr=00:16:3e:5d:aa:a8,vlan=0,model=lan9118,name=net0 -net tap,fd=23,vlan=0,name=hostnet0 -serial file:/var/log/libvirt/qemu/console.log -serial pty -msg timestamp=on
