Live migration not working when disabling IPv6 on Hyper-V host
Wednesday, May 5th, 2010Last week I was implementing a Hyper-V two node cluster with iSCSI storage. It was my first cluster with iSCSI instead of Fibre Channel storage. I Used the cluster validation tool and the result was OK. Things looked good. When I started testing the Live migration feature, it did not work ! I could do a quick migration but not live migration. SCVMM gave me the following message:
Error (10698)
Virtual Machine TEST could not be live migrated to virtual machine host HYPERV01 using this cluster configuration.
(unspecified error (0×80004005))
I will not bother you with the troubleshooting steps taken, but after enabling IPv6 on the NIC’s of the HYPER-V hosts used for managing the host, live migration worked fine.
So yet another reason why you should not disable IPv6 !!
