Linux Redhat and Live Migration Problem

-

hi all,

we've set simple hyper-v farm made of 2 server 2008 datacenter hosts - hv1 , hv2. we've got live migration working seamlessly our windows hosts - drop 2 ping responses , carry on if nothing ever happened.

however, when linux redhat 5 guest (installed integration components per ms documentation) live migrated it's network seems stop working. when happened tried ping both guest , out of guest no luck when ping ip address guest network becomes active again externally , internally.

has ideas why happen?

many thanks,

tim

hi tim

you need set mac (ethernet) address of virtual machine static.

vmm makes quite easy. 

failing set mac static can cause issues vm appears go offline.  there example of on ms support site (kb976724).  in scenario, sles 10 sp2 live migrates, changes mac address on new host , loses it’s ip configuration.  because linux distro binds ip configuration mac address.

 

if post helpful, please mark such
