How to avoid downtime when resizing virtual machines
- by Ivan Buttinoni
Many IaaS provider offer dynamic upgrade/downgrade of RAM and cores.
Usually a Linux VM has to be rebooted to apply these changes.
Sometimes, things like VMware tools or other guest services are well integrated so the upgrades to resources are immediately available, but the downgrades still need reboot.
How can I solve this issue, so that when downgrading resources I do not have to reboot my guests?
