Virtual Infrastructure Client - Windows interface lag

Posted on 2008-06-21

I have Windows XP virtual machines installed on a VMware ESX server.  I connect to these machines via VMware Infrastructure Client, however there is a significant interface lag. For example when clicking on a file, there is sometimes a second or two lag before the file becomes highlighted.

Note: the VM tools are installed, the hardware acceleration on the monitor is set to full, and the system's visual effect are set to "adjust for best performance."

Question: What can I do to reduce the lag?

Hi,

Do Have RDP enabled on the win XP box. If so can you try connecting to the XP machine using RDP and see.

The possible reason why you see a lag when you try to access the VM from the VI Client can be because that is delivered through the web interface and other connections are also on the same interface.

Also check inside the virtual machine the dispaly properties>>settings>>advanced>>troubleshoot and move the slider bar to full for "hardware acceleration"

I can't use RDP connection to the virtual machines, this is because the machines have to connect via VPN to other networks.  I already have the acceleration set to full.

The Virtual Infrastructure client requires .Net to be updated on the source machine - the one that you connect from.

Please update .Net frameworks and latests service packs from them and see if that helps your problem.

Is it only on Windows XP machines you have this issue with?

How is your VirtualCenter Management Server specc'ed with RAM and CPU and how many hosts and virtual machines does it manage?

I already have installed all of the latest .Net updates (see attached). We only have Windows based VMs.  Win 2003 has same symptoms.  The server has Dual processors Quad Core 2.8 Ghz.  It has 20 GB of RAM.  The VMs are only using 25 % of total resources (ex: it is only using 5.0 GB of total RAM).

No answer received.  Problem solved by putting QoS rules on firewall.
