Here I have a machine with VMware ESXi 5. One of my VMs is shutting down after some time (I can't prevent this). However, I want the VM to be automatically restarted if it was shut down. But I can't find an option in my vSphere client to do this.
So is there a way to do an automatic restart?
ESXi 5 has option to start and stop VM automatically
Go to ESX host configuration and left side you can see "Virtual Machine Startup/Shutdown"
Go to properties and select "Allow virtual machine to start and stop automatically with the system"
in Startup Order move your VM machine in "Automatic Startup section"

We are working on VMware and HA and DRS are enabled on a cluster. We want to set CPU threshold for every host i.e. if cpu utilization goes above 80% vm's move automatically.
Thanks in advance
Details
You receive an event message when the number of phisycal cpu on the host exceeds their limit.
This occurs when clients register more cpu on an ESXi host than the host can support.
Impact
If the limit is exceeded, the management agent is at risk of running out of system resources. Consequently, VMware vCenter Server might stop managing the corresponding ESXi host.
Solution
To ensure management functionality, restrict the number of Pcpu to the limit indicated by the VMkernel.Boot.maxPCPUS property of the ESXi host.
To lower the value of maximum number of allowed registered pcpu:
Edit the VMkernel.Boot.maxPCPUS variable by selecting the host in vCenter Server.
Open the Configuration tab and select Advanced Options in the Software box.
Expand the VMkernel option and click Boot.
Alter the value in the text box to the right of the VMkernel.Boot.maxPCPUS variable.
Hope to be useful ;)
I am looking for the VM Monitoring functionality in vsphere 6.0, I have followed some instruction found, but after all required steps to enable this functionality I don't know why I don't see the expected behavior:
"On" vSphere HA
Installed VMWare tools on guest environment
start VM
/etc/init.d/vmware-tools I have stopped the service <- so from now no Heartbeats are sent to Host machine
BUT Nothing happened.. What I expected here was a restart of VM.
What am I wronging?
Even If VM Monitoring is based also on VM's disk/network I/O I have used fork bomb, but nothing happened..
Below my configuration
Tks guys

I think FORK bomb will increase the computation not the freeze the Disk I/O or network drops.Try to stop the disk I/O and network I/O in the VM level.Hope that will be restart your machine.The VMware has build an intelligence to avoid the false restart trigger.
Refer Duncan's Blog more about the VM monitoring.

I am new person of vmware environment i have shutdown a physical server through
RDP but it is not properly shutdown when i was checked in the ILO. Please suggest
how to shutdown a physical server?
To forcefully shut down a server host through iLO, you will first need to log into the blade system where the host is located. From there, click the host and in virtual power option, there should be an option to power off the blade.
I am trying to get Micro Cloud Foundry working under Windows 7 64 bit with VMware workstation 7.1.4. For some reason, the VM starts with no eth0 only lo, therefore I never get a network connection. Ideas?
Do you have any other VMs running at the same time that may be using the same virtual adapter? Have you also checked the network settings on the VM to make sure a physical interface is selected on which to bridge the virtual adapter with.
As an alternate to deleting VM and starting from scratch again, and loose all your work, you could also rename the folder that contains the VM image. When relaunching VM from renamed folder, VMWare will ask whether you "copied" or "moved" this VM. Select the "I moved" option and then VMware will recreate the ethernet adapter configuration for you and you are good to go from then on
Two RAID volumes, VMware kernel/console running on a RAID1, vmdks live on a RAID5. Entering a login at the console just results in SCSI errors, no password prompt. Praise be, the VMs are actually still running. We're thinking, though, that upon reboot the kernel may not start again and the VMs will be down.
We have database and disk backups of the VMs, but not backups of the vmdks themselves.
What are my options?
Our current best idea is
Use VMware Converter to create live vmdks from the running VMs, as if it was a P2V migration.
Reboot host server and run RAID diagnostics, figure out what in the "h" happened
Attempt to start ESX again, possibly after rebuilding its RAID volume
Possibly have to re-install ESX on its volume and re-attach VMs
If that doesn't work, attach the "live" vmdks created in step 1 to a different VM host.
It was the backplane. Both drives of the RAID1 and one drive of the RAID5 were inaccessible. Incredibly, the VMware hypervisor continued to run for three days from memory with no access to its host disk, keeping the VMs it managed alive.
At step 3 above we diagnosed the hardware problem and replaced the RAID controller, cables, and backplane. After restart, we re-initialized the RAID by instructing the controller to query the drives for their configurations. Both were degraded and both were repaired successfully.
At step 4, it was not necessary to reinstall ESX; although, at bootup, it did not want to register the VMs. We had to dig up some buried management stuff to instruct the kernel to resignature the VMs. (Search VM docs for "resignature.")
I believe that our fallback plan would have worked, the VMware Converter images of the VMs that were running "orphaned" were tested and ran fine with no data loss. I highly recommend performing a VMware Converter imaging of any VM that gets into this state, after shutting down as many services as possible and getting the VM into as read-only a state as possible. Loading a vmdk either elsewhere or on the original host as a repair is usually going to be WAY faster than rebuilding a server from the ground up with backups.
