tests: extract hugepages-numa-default-dimm out of hugepages-numa Signed-off-by: Pavel Hrdina <phrdina@redhat.com> 2018-08-07 15:00:02 +00:00			`LC_ALL=C \`

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: command: Enforce setting XDG variables for system QEMU For session mode, only XDG_CACHE_HOME is set, because we want to remain integrating with services in user session, but for system mode, this would have become reading/writing to '/' which carries the obvious issue with permissions (also, '/' is the wrong location in 99.9% cases anyway).

qemu: Always assume QEMU_CAPS_REALTIME_MLOCK The '-realtime mlock' cmd line argument was introduced in QEMU commit v1.5.0-rc0~190 which matches minimal QEMU version we require. Therefore, the capability will always be present. Apparently, nearly none of our xml2argv test cases had the capability hence slightly bigger change under qemuxml2argvdata/.

qemu: Don't use -mem-prealloc among with .prealloc=yes https://bugzilla.redhat.com/show_bug.cgi?id=1624223 There are two ways to request memory preallocation on cmd line: -mem-prealloc and .prealloc attribute for a memory-backend-file. However, as it turns out it's not safe to use both at the same time. If -mem-prealloc is used then qemu will fully allocate the memory (this is done by actually touching every page that has been allocated). Then, if .prealloc=yes is specified, mbind(flags = MPOL_MF_STRICT \| MPOL_MF_MOVE) is called which: a) has to (possibly) move the memory to a different NUMA node, b) can have no effect when hugepages are in play (thus ignoring user request to place memory on desired NUMA nodes). Prefer -mem-prealloc as it is more backward compatible compared to switching to "-numa node,memdev= + -object memory-backend-file".
