p2v issues with original vm IP address

[AustinSw]

Hi I am experiencing issues after I have P2v hyper-v vm's to esxi 5.5 the migration process I am performing is p2v and not v2v as I need the migrate the customers existing iscsi drives mapped to the hyper-v host. Anyway his works fine however when I power up the migrated machine install VMware tools and remove the old nics I get dropped pings using the original IP address. However if I change the ip to something new  this ping fine. I had this on all 3 VMS I have converted and all different os levels windows 2012, windows 7 and windows 2008.

I am thinking this is maybe some cached either in the original hyper-v host or on the network. Anyone had this before or know how to resolve.

Many thanks

If you think it is cached , Go the Device manager --> tools --> view hidden devices

go to network adapter and remove the hidden or removed adapters from the server , (the hidden one will be grayed out , ) once you do that you will have the original NIC attached to the server functional

Hi thanks for your reply I tried this last night and removed the used nic's which where greyed out as I read this on a VMware KB article. This did not seem to make a difference even with a reboot after.

If there anywhere else where the old IP might be held in the VM? Tonight I am going to test by isolating the network to make sure that its not a switch issue. I will try pinging VM's which are on the same vSwitch.

Austin ,

try clearing the DNS entries, and flush the DNS entries

Make sure no Duplicate entries are not made for the two new VM

Hi,

Some question to come to the conclusion

1) Are you able to ping gateway after providing the IP address from the virtual machine ?

2) If you are trying to ping the VM with its hostname then to which IP address its showing ?

3) Trying to provide IP address having issue and then run a tracert through command prompt and check where its getting stuck

4) There are chances where you have registered the IP address and hostname in DNS server because of which it might getting clashes between the Old IP and VM name ?

Thanks all - Will try some of these and let you know how I get on tonight.  Cheers
