Objet : [Xen-users] about 10 min time between dom0 anb domU
Hey guys,
I have a problem on a domU "partdns01" which is actually acting as ntp/bind/dhcp server.
When i boot the domU the dhcpd deamon can’t start because of a too great time mismatch between him ans his failover peer.
For info, the dom0 name is "xendns01"

I already did that trick but without any luck :

partdns01 ~ # cat /proc/sys/xen/independent_wallclock

Same result with the follwing workaround :
