Last week I had some issues with starting virtual machines on vSphere 5.5 hosts (enough capacity available), when I try to start up the VM I receive message:

Could not start VMX: msg.vmk.status.VMK_NO_MEMORY”

An error was received from the ESX host while powering on VM [name]
Head globalCartel-1 already at its maximum size of 7869288. Cannot expand
Could not start VMX: msg.vmk.status.VMK_NO_MEMORY

Cause

This issue is caused by a memory leak in the driver which fills the SWAP memory of the ESXi host, making it unable to response to any requests at all. This issue occurs with ESXi hosts running on HP hardware with these versions of AMS:

• hp-ams 500.9.6.0-12.434156
• hp-ams-550.9.6.0-12.1198610
• hp-ams 500.10.0.0-18.434156
• hp-ams-550.10.0.0-18.1198610

Solution

This is a known issue affecting ESXi 5.x. To resolve this issue, upgrade to AMS version 10.0.1.

For ESXi 5.0 and 5.1, see:

• HP Agentless Management Service Offline Bundle for VMware ESXi 5.0 and vSphere 5.1.

For ESXi 5.5, see:

• HP Agentless Management Service Offline Bundle for VMware vSphere 5.5
• HP ESXi Offline Bundle for VMware vSphere 5.5

Note: In some cases, commands running on the ESXi host fails with cant’t fork.  In this case the virtual machines running on the ESXi host needs to be powered off and the ESXi host rebooted. To verify the installed versions of AMS, run this command:

esxcli software vib list | grep ams

To remove the package on all hosts running on these AMS versions:

1. Log in to the host using SSH. For more information, see Using ESXi Shell in ESXi 5.x and 6.0 (2004746).
2. Run this command to stop the HP service (does not persist on reboot):
   /etc/init.d/hp-ams.sh stop
3. Run this command to remove the VIB:
   esxcli software vib remove -n hp-ams
4. Reboot the host.

Few days ago I read some information about memory tweaking on my PC / USB ESXi 4.0 whitebox. I got the this hardware configuration at home:

• Asus P6T SE (HCL)
• Intel Core I7 920 2.66 GHz, 4.8 GT/s, 4x 256kb, 8 MB, Boxed
• OCZ Gold 6 GB, PC3-12800, 1600 MHz, 8, Non-ECC, Kit Of 3 
• OCZ Fatal1ty 700 Watt, 20+24 Pins, 80 Plus Rating
• Network Intel® PRO/1000 PT Dual Port Server Adapter
• 2x Samsung SpinPoint F1 1 TB, 7200 Rpm, 32 MB, S-ATA II/300
• Antec Gamersgear Twelve Hundred Black
• XFX GeForce GTX 275
• Samsung SH-S222A DVD-writer 22x
• Storage ESXi: cheap NAS, nothing special, only too slow

The OCZ Gold 3 stripes with 2 GB each are default rated on 1066Mhz, but they can communicate with 1600Mhz (triple channel!). Time to change some settings in the bios of my Asus P6T SE motherboard.
