620d6b328f virtio-net: increase defaults rx|tx-queue-size to 1024
This is reducing packet drop on high pps, and also needed for dpdk.

Redhat already have use it by default in rhev and his openstack platform too
since 2019.

I'm using it in production since 6 months, I don't have seen performance regression.

fix: (which ask for custom option, but setting it by default seem fine for me)

e5a6919c38 cfg2cmd: turn smm off when SeaBIOS and serial display are used
Since commit 277d33454f77ec1d1e0bc04e37621e4dd2424b67 in pve-qemu,
smm=off is no longer the default, but with SeaBIOS and serial display,
this can lead to a boot loop.

VM.
