Comment 29 for bug 1668129

For those watching this bug, to work around this until there is an AMI available that fixes it, you can disable udev memory hotadd by changing the /lib/udev/rules.d/40-vm-hotadd.rules file to comment out the memory hotadd rule, like this:

--- /lib/udev/rules.d/40-vm-hotadd.rules.old 2017-03-01 22:02:39.905314616 +0000
+++ /lib/udev/rules.d/40-vm-hotadd.rules 2017-03-01 22:02:46.797002312 +0000
