Greetings Vmware experts,
Fairly new to both Linux and Vmware. I am having an odd issue that I cannot isolate on Vmware Server 2.
My Server 2008 guest is intermittently dropping the network connection with a large data transfer. During network file transfer my physical Vista 64 will be at 96% network utilization on 100Mbps link for about a min or so. The network will then drop to 0% for 5 seconds and pick back up to 90%. This occurs about every 10 seconds after first network drop. The transfer picks back up to 90% at first but gets slower and slower to the point of dropping the connection all together.
I have been jumping back and forth between network card or a software RAID (I/O) issue. Been using the onboard Broadcom NIC and recently obtained a Intel Pro1000 PT hoping it would resolve my issue. It has not.
Also note that I have not been able to have OpenSuse11/Vmware Server 2 retain network configuration with Host reboot. I must run vmware-config.pl have vmnets available.
Any insight as to why this is happening would be most appreciated. This maybe my push to purchasing an Adaptec HW RAID and ESXi 3.5
I have a very simple whitebox Vmware server 2 setup.
Host: OpenSuse 11 2.6.25.18-0.1 (pae)
3 Guests total. For troubleshooting purposes I am running only my primary guest Server 2008 STD 32bit.
