The Xen PV shim requires a PV console; add that. Also update the Xen PV network support to the new XenDevice model so that it can be used with emulated Xen guests. Fix up the Xen block support to allow it to be used with '-device file=IMAGE,if=xen'. Update the documentation to reflect all of these, taking the opportunity to simplify what it says about q35, by making unplug work for AHCI. Ignore the VCPU_SSHOTTMR_future timer flag, and advertise the 'fixed' per-vCPU upcall vector support, as newer upstream Xen do. Fix a bug where net_cleanup() would remove the NIC from underneath the emulated network devices, which doesn't work well when network devices have their own destructors (as the Xen PV one has to, in order to clean up the XenStore nodes). v4: • Drop the fixes from the start of the series, which have been sent as a separate pull request (cc: qemu-stable): https://lore.kernel.org/qemu-devel/20231106103955.200867-1-dwmw2@xxxxxxxxxxxxx/ • Go back to the original, more hackish, version of making `-nic` work for Xen network. The better fix for that is not going to get through review before the soft freeze. • Fix the documentation so the docs can reference the '-initrd' command line option with newer Sphinx. • Improve the duplicate detection for Xen block devices to match all partitions and even the same disk number on different majors.
