Recently installed ESXi with latest updates on SuperMicro X7DB8 server.
Server config: Xeon E5310, 4GB of RAM, SAS RAID1 on LSI, 2x Intel 82572EI.
Guests: Debian Etch (kernel 2.6.18-686), Windows server 2008 Stadart.
Debian is working as gateway for LAN . Windows server acting as domain controler on LAN.
Problem - random connetivity lose between guests. Picture of ESXi networking config attached.
First I noticed DNS resolution problems on Windows servr, coz it uses forwarders from outside. When I found ping timeout to Debian guest.
After I found same lose from Debian to Windows server. Both guests are on the same virtual swicth.
So I began testing with pinging both guests from LAN machines and at the same time I started ping between guests.
No ping lose from LAN machines to both guests, while ping lose occurs between guests!
