qemu: Prefer hugepages over mem source='file' https://bugzilla.redhat.com/show_bug.cgi?id=1214369 Consider the following XML: <memoryBacking> <hugepages> <page size='2048' unit='KiB' nodeset='1'/> </hugepages> <source type='file'/> <access mode='shared'/> </memoryBacking> <numa> <cell id='0' cpus='0-3' memory='512000' unit='KiB'/> <cell id='1' cpus='4-7' memory='512000' unit='KiB'/> </numa> The following cmd line is generated: -object memory-backend-file,id=ram-node0,mem-path=/var/lib/libvirt/qemu/ram, share=yes,size=524288000 -numa node,nodeid=0,cpus=0-3,memdev=ram-node0 -object memory-backend-file,id=ram-node1,mem-path=/var/lib/libvirt/qemu/ram, share=yes,size=524288000 -numa node,nodeid=1,cpus=4-7,memdev=ram-node1 This is obviously wrong as for node 1 hugepages should have been used.

qemu: command: Override HOME variable for system QEMU By default, qemu user's home dir points to '/' which shouldn't be used at all. We therefore pass the HOME variable from the current variable iff not running as SUID, which means that for systemd we never set it. This patch makes sure, that for system QEMU this is always set to libDir/<driver>, session mode is left untouched. Signed-off-by: Erik Skultety <eskultet@redhat.com> Reviewed-by: Daniel P.

qemu: Switch to -accel We currently use -machine accel=XXX which is just a syntax sugar for -accel XXX. The former doesn't allow specifying arguments for accelerator, because all arguments passed to -machine are treated as arguments of machine itself. The -accel argument was introduced in QEMU commit v2.9.0-rc0~70^2~19 and since our minimum required version is newer (2.11.0) we can safely assume its existence and use it without any capability.

qemu_command: Generate memory only after controllers Currently, memory device (def->mems) part of cmd line is generated before any controller. In majority of cases it doesn't matter because neither of memory devices live on a bus that's created by an exposed controller (e.g. there's no DIMM controller, at least not exposed). Except for virtio-mem and virtio-pmem, which do have a PCI address. And if it so happens that the device goes onto non-default bus (pci.0) starting such guest fails, because the controller that creates the desired bus wasn't processed yet. QEMU processes arguments in order. For instance, if virtio-mem has address with bus='0x01' QEMU refuses to start with the following message: Bus 'pci.1' not found Similarly for virtio-pmem. I've successfully tested migration and changing the order does not affect migration stream.

qemu: caps: Always assume presence of 'ide-hd' and 'ide-cd' devices The split of ide-disk into the two separate devices was introduced by qemu commit 1f56e32a7f4b3 released in qemu v0.15. Note that when compared to the previous commit which made sure that no disk related tests were touched, in this case it's not as careful. Signed-off-by: Peter Krempa <pkrempa@redhat.com>
