We just installed Veeam on a customers server (standalone Hyper-v 2012). They are runing two vms, a dc and rds-server.
After installing Veeam the dc01 servers freezese 2-3 daily, with absolutely NO ssign in in the eventviewer in hper-v host or the vm itself. The other vm works all the time.
It is very strange but as this happened at the same time we installed Veeam9 the customer of crouse wonder what we did install..
I have read a few blogpost mention that it could be that the virtual harddrive is connected to scsi instead of ide.
Have anyone seen this behavior related to Veeam or another backupsoftware which can cause this?
