2008 R2 VM hangs on file copy...
hi all,
i'm have following configuration (there's lot more simplified/consise version):
hp dl380 g6 connected lefthand san (iscsi)
2008 r2 server core installed hyper-v role
2 vm's - both 2008 r2 (1 dc other running scvmm). vhd's on san.
the issue i'm having during file copy dc to the scvmm server (an iso file or 2) one of servers hang - no blue screen, the network drops out (can't ping) , logging server via hyper-v manager connection either slow or hangs. managed the 'hung' server using different admin account , interstingly enough nic showed disabled. tried kill off other user session in task manager task manager ended 'not responding'. way to get server turn off , start again. i've tried logging dc , opening c$ on scvmm server to do copy - scvmm server hangs. if i do other way dc hangs. host server seems fine, remaining vm fine. there no event log messages, no blue screen - little go on.
i've got 12 other servers in various cluster/standalone configurations same hardware and drivers/firmware etc (all newest versions) , haven't seen same problem (yet!).
on doing reading there issues broadcom nics (and toe etc - though i'm under impression lot of has been dealt in r2). have suggestions of start (or having similar problems)?

hi,
in order isolate issue, please perform following suggestions:
1. please boot both dc vm , scvmm vm safe mode networking test whether same issue.
2. please check have tcp offloading , other offloading disabled on nic, these function may cause network problem.
3. please create internal virtual network or private virtual network, connect both vm same virtual network , test whether same issue.
by way, did same issue other vms?
