we're trying to see if we can xm save like we did on lion, unlike we did on boar, but it's a pretty old box, so we might be rebooting you. 

[root@hydra /]# uptime
 18:56:26 up 410 days, 15:44,  2 users,  load average: 0.09, 0.29, 0.25 going down shortly

just like lion, save for that there are fewer customers on boar.

[root@boar ~]# uptime
 16:24:55 up 410 days, 15:32,  3 users,  load average: 0.00, 0.01, 0.00

[root@boar ~]# xm list |wc -l

starting upgrade now (service won't be impacted until we start the reboot)

all servers will be rebooted (as lion was today)  for some kernel upgrades, and to consolidate all my servers to one rack.  

~20 min network outage today

from 11:58 to 12:19 PST  -  We suspect upstream network trouble as the cause. 
root@lion ~]# uptime
 18:12:12 up 451 days, 17:42,  8 users,  load average: 0.01, 0.03, 0.00

as usual, if we don't screw it up it will be 20 minutes downtime and no reboot for you, due to xm save/restore network outage tonight

I screwed up. I gave two customers the same IP and mac address. this took down the network. the problem should be fixed now

as far as I can tell we were down about two hours. 

yeah.  so sata_nv doesn't hot swap on the 2.6.18 xen kernel that comes with xen 3.3.  ugh. 

if nothing goes too badly, you won't notice the reboot;  your host will only be unreachable for
a few minutes, you will not actually experience a reboot.
