Bug description:
[impact]
40-vm-hotadd.rules unconditionally tries onlining memory, which
results in logged error messages if the memory is already online
[test case]
since this rules file restricts operation to only hyper-v or xen
guests, boot a hyper-v or xen vm guest, and check for logged error
msgs like:
Apr 29 22:36:46 focal01 systemd-udevd[266]: memory7:
/usr/lib/udev/rules.d/40-vm-hotadd.rules:9 Failed to write
ATTR{/sys/devices/system/memory/memory7/state}, ignoring: Invalid
argument
alternately, to test on a vm guest other than hyper-v or xen,
comment/remove the 'GOTO="vm_hotadd_end"' line from the rules file and
reboot.
[regression potential]
as this adds a check before attempting to online memory for hyper-v
and xen vm guests, any regression would likely involve failure to
correctly online all memory on those guest platforms.
[scope]
this rule has been around for a long time, so is needed for x/b/f/g.
[original description]
In focal, udev's 40-vm-hotadd.rules (from debian/extra/rules-ubuntu)
tries to write to invalid (as of 5.4.0-1010-azure) sysfs nodes
resulting in warnings such as:
Apr 29 22:36:46 focal01 systemd-udevd[266]: memory7:
/usr/lib/udev/rules.d/40-vm-hotadd.rules:9 Failed to write
ATTR{/sys/devices/system/memory/memory7/state}, ignoring: Invalid
argument
Perhaps 40-vm-hotadd.rules needs to be updated for 5.4 semantics,
removed, or something else. This behavior is present on systems
upgraded from 18.04 (via d-r-u) as well as new focal systems, upon
first reboot of the VM.
udev: 245.4-4ubuntu3
