HI Xianhui,

 We are trying XCP and want to use it in our production environment,

It’s really a perfect project!!

But we have a strange problem now.

When we try to move a XCP Hypervisor from Pool A to Pool B,

You could tried to pif-forget and pif-introduce the network interface as per the following doc : http://support.citrix.com/article/CTX121615

However the easiest thing to do when moving a server from one pool to another, I think, is to get the host out of the pool, re-install it and join it to the new pool. It should take 5-10 minutes. If the servers is on the other side of the island and you don't have advanced ipmi/ilo card for re-install, then it is another story.

Cheers,

Denis



Then it lost the network connection, and we use console to check XCP
Hypervisor,

The XCP Hypervisor console shows it cannot find any Host NIC,

We try to use xe-reset-networking, and after reboot, the first NIC is on
but xsconsole still not show the NIC

I paste the /etc/firstboot.d/log/30-prepare-networking.log, and find
some log :

+ unset MODE IP NETMASK GATEWAY DOMAIN PIF LABEL

+ for iface in '${INTERFACES}'

+ '[' '!' -e /etc/firstboot.d/data/interface-68:b5:99:79:f6:18.conf ']'

++ /opt/xensource/bin/xe pif-list params=uuid MAC=68:b5:99:79:f6:18

Error: Connection refused (calling connect )

Is there anyone have the same problem?

Or can give some poing to figure out what happen?

Thanks a lot!!!!

Klein,
