hi...

What I can see is that the host has no redundant power supply which gives u that warning..
if applicable, try to fix this problem and see..
for the time issue u either can set it manually or configure a NTP server for it through:

VMware KB:    Configuring Network Time Protocol (NTP) on ESX/ESXi hosts using the vSphere Client 

Hope it helps

For time issue in ur vm..install vmware tools then go to vm settings options tab check the box that sync the vm time with the host...

For power supply redundancy...check if ur server has two operating power supplies and connected...

I hope Im a good hand for u..and please don't forget points if Im

Editing Kernel Configuration

Kernel command line parameters are specified in the /etc/lilo.conf or /boot/grub/grub.conf file, depending on your choice of boot loader.

For LILO, put the kernel command line parameters at the end of the append line. For example, if the append line looks like:

append="resume=/dev/hda6 splash=silent"

and you want to add clock=pmtmr divider=10, the updated text is:

append="resume=/dev/hda6 splash=silent clock=pmtmr divider=10"

Remember to run /sbin/lilo after editing lilo.conf, so that your edits take effect.

For GRUB, put the kernel command line parameters at the end of the kernel line. For example if the kernel line looks like:

kernel /vmlinuz-2.6.18 ro root=/dev/hda2

and you want to add clock=pmtmr divider=10, the updated text is:

kernel /vmlinuz-2.6.18 ro root=/dev/hda2 clock=pmtmr divider=10

For additional information about working with boot loaders, see your Linux distribution's documentation.

This helps u..?!?!!

Hi,

We can't  see if your vmware tools are installed on your VM, can you check on the summary tab ?

Then you are synchronizing your Red Hat with your ESX.  You can unselect this option.

The time configured in your host is correct?

you can check on the configuration tab --> time configuration.

Regards,

Julien

julien,

ya in summary i don't have vmware tools like u.

for the default time sync setting not tick, and now i try to tick.

time configuration in vSphere is correct.

[muuel09]

ok i'll check first bro tq for u'r help :smileygrin:

[julienvarela]

So you need to install the vmware tools.

Regards,

Julien

muuel..share plz a screenshot of this VM summary tab..

[muuel09]

this is what u mean?

or this

[ShadyMalatawey]

The same tab (Summary) of the VM itself..instead of selecting the host..just select the VM itself (vhp live) and selkect the same tab (Summary)..
