We are migrating our older esx hosted machines from Intel processor based hardware to AMD. The migration seems to go just fine, however, on power up, we are getting dcom errors and no network connectivity. Is this common? Hoping there is an easy fix.
Thanks

I regularly move between the two processors. The machines must power down first however. Have you updated tools?
Yes, I updated the tools and powered down the guest. On the AMD host, I get errors. If I move it back to the intel host, everything is fine.
Your hardware is on the HCL??
Yes. HP DL365 G2 attached to NX4 for the destination host. Origination machine is HP ML370 G4 local disk and NX4.
The only thing that is different, which I wouldn't think would be a problem is that the origination machine is not up to the latest patches, while the destination is.

I see the following in the system event log. Only on the AMD hardware.
Event Type: Information
Event Source: DCOM
Event Category: None
Event ID: 10026
Date: 7/6/2009
Time: 5:24:17 PM
User: N/A
Computer: PELIASVC-SAI
Description:
The COM sub system is suppressing duplicate event log entries for a duration of 86400 seconds. The suppression timeout can be controlled by a REG_DWORD value named SuppressDuplicateDuration under the following registry key: HKLM\Software\Microsoft\Ole\EventLog.
I was able to move the server, albeit not in the fashion that I wanted. I booted the VM with a coldclone iso and cloned it to the AMD hardware. In doing it this way, i receive no errors in the OS and all seems fine.
It is not the best solution, but it works. If anyone else has ideas, I am open for suggestion. I will probably open a ticket with VMware. And will post the solution, if any they supply me with.
Are you able to move it back to the Intel machine?
Yes, I can move it back to the intel machine. Everything works happily there.
Were the machines P2V to the Intel machine? Perhaps some leftover hardware drivers?
No.. this was built in a VM. vmware is suggesting reinstalling the tools, but this didn't help.
I just noticed something - ESXi tools includes two network drivers,
"VMware PCI Ethernet Adapter" - vmxnet.inf, and
"VMware Accelerated AMD PCNet Adapter" - vmware-nic.inf
Might be worth manually removing the intel driver (I presume the first one) and then redetecting the hardware, which presumably will find the AMD driver?
Good idea J1mbo. But, alas, this did not resolve the problem either.
