You can change the amount of RAM in your BigV virtual machine at any time, but you will need to shut it down briefly to upgrade. To set the amount of memory for vm 'web1' to 4096MB (4GiB), you should run:

bigv vm memory web1 4096

This will have an effect the next time the machine is rebooted. If you bring the amount of memory down you should find the memory shrinks straight away (this can crash your machine quickly if there's not enough to run your current workload).

BigV prices are dependent on memory, and each gigabyte costs £10 per month or £100 per year. You will also get a corresponding number of CPU cores to go with your RAM. Check the price list to see what your machine spec will cost when BigV is out of (β) .

Selecting a VM in another group

If you need to specify a VM in another group, you can do so like this:

bigv vm memory web1 4096 --group-name snowbother
