Force Virtual Machine on ESX to boot into BIOS

I was trying to figure out how can we force boot the Virtual machine into BIOS mode. When VM’s is powered boot screen changes so fast that you can not even see the text. It directly goes into PXE. Some blogger suggested to make changes in VMX file so that it can force it to go into BIOS. Why I wanted to go into BIOS ? Because I wanted to boot it through ISO but for some reason it was not. ISO was also bad for some reason. It was not a big thing but was talking long time to figure out. I also learned that either ESC or F12 Key can also help VM to boot into BIOS.

Finally there were settings on then VM itself which will boot the machine into BIOS. But this setting has to be set every time when VM has to booted into BIOS.

While leaving my previous work place I had a great time. Some moments to share with every one who visit my blogs and also to show them that I have started learning “Movies making”

HA Advance feature

Some of the HA Advance feature is smartly stolen from Help file and some are from
vmug.

Configuring Advanced HA Options

The Advanced Options (HA) dialog box lets you set advanced configuration options for HA.

To set advanced options for HA

1. In the Cluster Settings dialog box, select the VMware HA option.

1. Click the Advanced Options button to open the Advanced Options (HA) dialog box.

1. Enter each advanced attribute you want to change in a text box in the Option column and the value it should be set in the Value column.

1. Click OK.

The following table lists some of the available advanced HA attributes.

Attribute	Description
das.isolationaddress	Sets the address to ping to determine if a host is isolated from the network. If this option is not specified, the default gateway of the console network is used. This default gateway has to be some reliable address that is available, so that the host can determine if it is isolated from the network.
das.defaultfailoverhost	If this is set, HA tries to fail over hosts to the host specified by this option. This attribute is useful to utilize one host as a spare failover host, but is not recommended, because HA tries to utilize all available spare capacity among all hosts in the cluster. If the specified host does not have enough spare capacity, HA tries to fail over the virtual machine to any other host in the cluster that has enough capacity.
das.failuredetectiontime	Changes the default failure detection time (with a default of 15000 milliseconds, or 15 seconds). This is the time period when a host has received no heartbeats from another host, that it waits before declaring the other host dead.
das.failuredetectioninverval	Changes the heartbeat interval among HA hosts. By default, this occurs every second.
das.usedefaultisolationaddress	By default, HA uses the default gateway of the console network as an isolation address. This attribute specifies whether that should be used (true|false).
das.poweroffonisolation	Changes the default cluster behavior for Isolation Response. By default, the Isolation Response is to power off a virtual machine when a host is isolated from the network (true).
das.restartpriority	Changes the restart priority for the cluster. Options are disabled|low|medium|high. Default is medium.
das.vmMemoryMinMB	Specifies the minimum amount of memory (in megabytes (MB)) sufficient for any virtual machine in the cluster to be usable. This value is used only if the memory reservation is not specified for the virtual machine and is used for HA admission control and calculating the current failover level. If no value is specified, the default is 128MB.
das.vmCpuMinMHz	Specifies the minimum amount of CPU (in megahertz (MHz)) sufficient for any virtual machine in the cluster to be usable. This value is used only if the CPU reservation is not specified for the virtual machine and is used for HA admission control and calculating the current failover level. If no value is specified, the default is 128MHz.
das.failuredetectioninterval	<millisecs>
das.failureinterval	<millisecs>
das.tracelevel	0 | functiontracing
das.traceoutput	stdout
das.consoleperm	perm_all | perm_oper | perm_user
das.consolenode	<fqdn>
das.consoleuser	<username>

OSI model and IP Subneeting

Every time I use to go for interview and I have to struggle to find for document about OSI layer and Network Subnetting. So I thought of putting it on my blog and let be remain for ever on my website.
