Error: qemu-system-aarch64: Expected key=value format, found +invtsc

Hello,

i try to start a virtual machine on a raspberry pi (revolutionpi, Debian 12.2.0-14) and get this error:

Launching debian-vm
Error: Failed instance creation: Failed to run: forklimits limit=memlock:unlimited:unlimited fd=3 fd=4 -- /opt/incus/bin/qemu-system-aarch64 -S -name debian-vm -uuid 68e9508e-0191-4323-95e1-d8cce2b2aa78 -daemonize -cpu host,migratable=no,+invtsc -nographic -serial chardev:console -nodefaults -no-user-config -sandbox on,obsolete=deny,elevateprivileges=allow,spawn=allow,resourcecontrol=deny -readconfig /run/incus/debian-vm/qemu.conf -spice unix=on,disable-ticketing=on,addr=/run/incus/debian-vm/qemu.spice -pidfile /run/incus/debian-vm/qemu.pid -D /var/log/incus/debian-vm/qemu.log -rtc base=2025-06-02T15:23:48 -smbios type=2,manufacturer=LinuxContainers,product=Incus -runas incus: : exit status 1

when i look at the qemu.log of the machine:

qemu-system-aarch64: Expected key=value format, found +invtsc.

i am using the version from zabbly.

Thank for your help!

EDIT: i installed incus 6.0.3, added a memory limit to the instance and it is running. Up upgraded to incus 6.13 and get the same error about +invtsc

If using the Zabbly packages, please update again, a fix for this was cherry-picked earlier today.
