Hi,
Does anyone know or has anyone heard or seen any issue using the VMXNET3 driver with Windows 2003 R2?
We're running ESXi 5.5 with a mix of Windows and Linux guests. We have migrated everything from VMware Server 2 using the VMware vCenter Converter to bring everything up to VM version 10. VMware Tools have been installed.
Since the migration, the Windows guests have been very unstable:
* Windows 7 guest has 'locked' or 'frozen' once and we had to reboot the host to get it back up and running
* Windows 2003 Server R2 guest has also 'frozen' requiring a reboot of the host
* A different Windows 2003 R2 guest is crashing and rebooting with a TCPIP issue.
All three guests are configured with the VMXNET3 Adapter Type. All three machines have experienced 'lockup'. Last night both the Windows Server 2003 R2 guests have crashed and rebooted on STOP ERROR 7f.
I have analysed the crash memory dump for both Windows Server 2003 R2 guests and they both point the finger directly at vnetflt.sys. The guests are configured with Adapter Type VMXNET3 and the underlying hardware on the ESXi host is an Intel 82599EB 10-Gigabit SFI/SFP+. The guests' interfaces come up using the vmxnet3 Ethernet Adapter driver version 1.5.1.0 (vmxnet3n51x86.sys) and report 10Gbps speed. Also the check-box for power management is on ('Allow the computer to turn off this device to save power' option). Perhaps that should be switched off?
Can anyone say or does anyone know or has heard about problems with the vnetflt.sys. Is it a component of the VMXNET3? Should I be using a different driver?
Any clues are much appreciated.
Kind regards,
Tom
