For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now. If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or please mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience. ** Changed in: qemu Status: New =3D> Incomplete -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1877015 Title: virtio only support packed ring size power of 2 Status in QEMU: Incomplete Bug description: Issue discription=EF=BC=9A When QEMU starts with "-device virtio-net-pci,netdev=3Dnetdev0,mac=3D52:5= 4:00:00:00:01,disable-modern=3Dfalse,mrg_rxbuf=3Don,rx_queue_size=3D1025,tx= _queue_size=3D1025,mq=3Don,vectors=3D15,packed=3Don" It raises error: Invalid rx_queue_size (=3D 1025), must be a power of 2 between 256 and 1024 Analysis: According to virtio1.1 spec, the packed queue size value does not have to= be a power of 2.
