HVMBootParam

[Adam Mersva1709164055]

Hi Everyone

I would like to change the boot order and the CPU usage alart on 400+ machines.

I'm here, that this should work, but it does not work. What is the command what is actually working?

==================================

$HVMBootParams = @{
    "firmware," = "uefi"
    "order," = "n"
}

set-xenvm -name "%VMNAME%" -HVMBootParams $HVMBootParams

==================================

 

I already tried so many different combinations, but so far nothing is working.

Could anyone tell me how to run this?

 

thank you

The command looks correct, but the syntax does not look PS compliant. The hash table should be declared as follows:

$HVMBootParams = @{ "firmware" = "uefi";"order" = "n"}

i.e. with semicolon separating the pairs and no commas within the keys.

Also, use $VMNAME for the name variable.

Thank you the answer. 

In the meantime I foung out that the problem is not with the command, but I need to use the UUID and that will do the job

The command works using the  -Name too, as long as the variable is passed in correctly:

PS> $vmName="myVM"
PS> get-xenvm -name $vmName | select HVM_boot_params

HVM_boot_params
---------------
{[order, cd], [firmware, uefi]}

PS> $HVMBootParams = @{ "firmware" = "bios";"order" = "n"}
PS> set-xenvm -name $vmName -HVMBootParams $HVMBootParams
PS> get-xenvm -name $vmName | select HVM_boot_params

HVM_boot_params
---------------
{[order, n], [firmware, bios]}
