We are having a problem where a Suse v11 SP3 guest on Hyper-V 2012 seems to be having intermittent connectivity issues.
Essentially we run a Suse VM which hosts our DataSync Product. Since Upgrading to SP3 and migrating from Vmware ESX to Hyper-V we have been having problems where occasionally network traffic to the VM is interupted every few hours for a few seconds. We aren't exactly sure how often but this is our best guess.
What is strange is that if we ping to or from the guest to or from outside the VM the issue doesn't seem to happen either at all or so infrequently as to cause no issues.
We aren't really sure how we can figure out what the issue is and fix it once and for all, we don't want to run a ping forever.
