My client has a XenServer 6.0.2 installation with 2 Window Server 2008 R2 virtual machines.
Whenever the virtual machines are rebooted they lose their IP settings (IP address, subnet, gateway). Each time after a reboot I need to login to each VM via XenCenter and re-apply the required static IP settings.
This causes issues with connected iSCSI drives within each VM - drives need to be reconnected after each reboot.
For example, a network adapter has the following settings pre-reboot:
Description . . . . . . . . . . . : Citrix PV Ethernet Adapter #0
Physical Address. . . . . . . . . : C6-FB-A2-4F-2C-F3
IPv4 Address. . . . . . . . . . . : 10.101.0.101(Preferred)
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.101.0.10
DNS Servers . . . . . . . . . . . : 10.101.0.100
NetBIOS over Tcpip. . . . . . . . : Enabled
Post-reboot:
Description . . . . . . . . . . . : Citrix PV Ethernet Adapter #0
Physical Address. . . . . . . . . : C6-FB-A2-4F-2C-F3
Autoconfiguration IPv4 Address. . : 169.254.153.174(Preferred)
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :
DNS Servers . . . . . . . . . . . : 10.101.0.100
NetBIOS over Tcpip. . . . . . . . : Enabled
Under XenCenter --> Virtual Network Interfaces, each adapter is set to a static MAC address (i.e. "Use this MAC address").
I have tried the following commands within one VM but this had no effect:
netsh winsock reset catalog
netsh int ip reset
Can someone please help?
