For easier debugging this can be reproduced on any affected system (Tried KVM and EC2) by just running:
$ sudo systemctl start hv-kvp-daemon.service ^^ This will stall while one would assume it should quick-exit due to the ConditionVirtualization not being met. A full cycle (90 second stall) of this start-try in the journal will look like: Apr 06 09:17:01 ip-172-31-16-15 sudo[2290]: ubuntu : TTY=pts/1 ; PWD=/home/ubuntu ; USER=root ; COMMAND=/usr/bin/systemctl start hv-kvp-daemon.service Apr 06 09:17:01 ip-172-31-16-15 sudo[2290]: pam_unix(sudo:session): session opened for user root(uid=0) by ubuntu(uid=1000) Apr 06 09:17:01 ip-172-31-16-15 CRON[2294]: pam_unix(cron:session): session opened for user root(uid=0) by (uid=0) Apr 06 09:17:01 ip-172-31-16-15 CRON[2295]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) Apr 06 09:17:01 ip-172-31-16-15 CRON[2294]: pam_unix(cron:session): session closed for user root Apr 06 09:18:31 ip-172-31-16-15 systemd[1]: sys-devices-virtual-misc-vmbus\x21hv_kvp.device: Job sys-devices-virtual-misc-vmbus\x21hv_kvp.device/start timed out.
