Bug ID: 234134
Summary: Increase VM_MAX_NAMELEN value
Product: Base System
Version: 11.2-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
Currently VM_MAX_NAMELEN is set to 32 and thus the maximum length of virtual
machine is 31 characters.
We’re building product that uses bhyve to run virtual machines and we wanted to
use UUIDs as names for VMs.
UUID with hyphens has 36 characters and without it has 32 characters. Can this
limit be increased to 33 and
ideally to 37 or more characters?
For comparison qemu-kvm+libvirt allow for virtual machines with names that are
over 240 chars.
I've tested hypervisor with VM_MAX_NAMELEN to 64 on stable/12 branch and didn't
experience any issue.
