google compute engine - Booting from custom image in GCE. Boot hang at "Booting from 0000:7c00" -

i doing training on big data , since based on cloudera platform downloaded cloudera quickstart vm virtual box.

i don't have enough hardware open laptop decided try out gce. followed instructions convert virtual box images raw , tar.gz google gce bucket.

until point, went fine.

i able crate new instance , attached disk created out previous instance without issue.

after booting instance realized unresponsive, , external ip not reachable. looked @ serial console , found out shows messages until ""booting 0000:7c00" , nothing. seems boot issue related disk maybe...

i tried mounting disk secondary 1 working instance in gce , able see contents. disk seems ok. see below outputs lvm commands.

what going wrong vm? thanks!

found solution.

the disk must include 1 partition (root) boot directory in instead of boot partition had before.

i not 100% sure gce has problems booting logical volumes (lv). should avoid building new partition , dd data lv root partition standard ext partition.
