VMWare 6.5 Specific VM Running Causes Entire Hardware Node to Run Outrageously Slow

[ZaxAmusements]

Hi Community,

We have one particular VM we are running which is fairly light weight, running Windows Server 2012 R2

VM Specifications are as follows

4 Cores

16GB Ram

100GB HDD

When the VM is powered on, it seems to bring the entire box to almost a halt, everything runs slow and grinds to a halt

Any suggestions or comments would be appreciated.

Hi there,

I would check if:

- reservations are configured

- VM and hosts statistics // ESXTOP to check the behaviour of the ressources

- migration to another host show the same result

- snapshot chain on the VM

- are additional configuration defined at the VM level

Which hypervisor version are you running? On which hardware? Any unsupported configurations?

Best regards

Hi Wonlliv

Reservations are configured correctly.

Ive checked the Host's statistics and everything appears fine here, 

Ive not literally moved this VM yet.. as our only other ESXI Box is fairly full and running important applications and processes each day,   May need to spin up a DEV Box for testing....

We dont use snapshots anymore,  Our Veeam does but deletes it after

No abnormal configurations defined for this VM instance

We are running ESXI 6.5 on a SuperMicro Build with an Intel E5 1650 CPU and 48GB Ram with 4 x WD Gold Drives in a Raid 10 on an LSI Raidcard

Hope this helps give a better picture here.  Please let me know.

Greetings,

does the HCL says anything about an incompatibility?

VMware Compatibility Guide - System Search

Have you checked if you power settings at the BIOS level is set to "performance"?

Setting up a DEV box would be great to know if this behaviour is specific to this host.

Best regards!
