tests: redo test argv file line wrapping Back in commit bd6c46fa0cfe275c24debc1152cfc5206c04b59b Author: Juerg Haefliger <juerg.haefliger@hp.com> Date: Mon Jan 31 06:42:57 2011 -0500 tests: handle backspace-newline pairs in test input files all the test argv files were line wrapped so that the args were less than 80 characters. The way the line wrapping was done turns out to be quite undesirable, because it often leaves multiple parameters on the same line. If we later need to add or remove individual parameters, then it leaves us having to redo line wrapping. This commit changes the line wrapping so that every single "-param value" is one its own new line. If the "value" is still too long, then we break on ',' or ':' or ' ' as needed. This means that when we come to add / remove parameters from the test files line, the patch diffs will only ever show a single line added/removed which will greatly simplify review work.

qemu: assume -name is always available The -name arg was added in QEMU 0.9.1, so the QEMU driver can assume it is always available. Signed-off-by: Daniel P. Berrange <berrange@redhat.com> 2015-11-06 14:29:41 +00:00			`-name QEMUGuest \`

qemuBuildMemoryBackendStr: Report backend requirement more appropriately So, when building the '-numa' command line, the qemuBuildMemoryBackendStr() function does quite a lot of checks to chose the best backend, or to check if one is in fact needed. However, it returned that backend is needed even for this little fella: <numatune> <memory mode="strict" nodeset="0,2"/> </numatune> This can be guaranteed via CGroups entirely, there's no need to use memory-backend-ram to let qemu know where to get memory from. Well, as long as there's no <memnode/> element, which explicitly requires the backend. Long story short, we wouldn't have to care, as qemu works either way. However, the problem is migration (as always). Previously, libvirt would have started qemu with: -numa node,memory=X in this case and restricted memory placement in CGroups. Today, libvirt creates more complicated command line: -object memory-backend-ram,id=ram-node0,size=X -numa node,memdev=ram-node0 Again, one wouldn't find anything wrong with these two approaches. Both work just fine. Unless you try to migrated from the older libvirt into the newer one. These two approaches are, unfortunately, not compatible. My suggestion is, in order to allow users to migrate, lets use the older approach for as long as the newer one is not needed.
