I've just verified on saucy daily images that this seems to be work-aroundable
by launching with user-data containing a boothook that will run ethtool -K eth0
gso off.
example cloud-config:
#cloud-config
apt_update: true
apt_upgrade: true
packages: [ pastebinit ]
output: {all: '| tee -a /var/log/cloud-init-output.log'}
bootcmd:
- [ ethtool, -K, eth0, gso, "off" ]
So far though, I'm 2 for 2 in reproducing bug 1201567 (300 second scsi
timeout before / is mounted RW), that results in a over 5 minutes before
instance is reachable.
