vCenter 5.1 delay when opening vm console

[rvdl]

Last week we updated our vCenter Server from 5.0 to 5.1. And since that moment we experience some delay while opening vm console windows.

We used to have a black screen for about 1 or maybe 2 seconds before we got to see our vm console screen.

But now we have to watch a black screen  9 to 10 seconds before we get to see our vm console.

Has anyone got any ideas what i can do to speed up this process?

One weird thing i noticed.

In the vCenter database we used to have the following tables.

VPX_HIST_STAT1

VPX_HIST_STAT2

VPX_HIST_STAT3

VPX_HIST_STAT4

But now i see these tables are not here anymore, instead i see a lot of new tables.

VPX_HIST_STAT1_1

VPX_HIST_STAT1_2

VPX_HIST_STAT1_3

etc.

and also

VPX_HIST_STAT2_1...

VPX_HIST_STAT3_1...

VPX_HIST_STAT4_1...

etc

I have no idea if this have something to do with each other, but i can't check the fragmentation of the performance history anymore.

use vCenter5
go
dbcc showcontig (VPX_HIST_STAT1)
go

Gives error: Msg 5239, Level 16, State 1, Line 1
Unable to process object ID 2102298549 (object 'VPX_HIST_STAT1') because this DBCC command does not support objects of this type.

Any help would be appreciated, thank you.

Hi, I have been battling with this specific issue for more than a year. I've just upgraded our farm to 5.5 and was experiencing exactly the same issue again.

Eventually after trying everything I've been able to identify the cause.

I had VMware Workstation (version 10) installed on my Windows client. As soon as I uninstalled VMware workstation, console access of VMs (either via the Web client or the vSphere client) is more or less instant (it was consistently around 10-15 seconds before).

VMware - please can you urgently look at this conflict. I've wasted so much time trying to get to the bottom of this!

Hope this helps someone else.
