Hi all,
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,
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 ']'
+ source /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 --minimal
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,

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.
