Limits & validation reference

The field rules and fixed limits the WebUI and API enforce. Values here are the platform’s only hard limits — all other capacity is governed by per-tenant quotas.

How validation works

Every input is validated twice: the WebUI checks it for fast feedback, and the API re-checks it as the security boundary. The two use identical rules.
Values are trimmed of surrounding whitespace; email is stored lower-case; enum values are normalised; passwords, tags and keys preserve case.
When a value is rejected, the field shows the message in the last column below.

Names & identity

Field	Rule	Pattern
Email address	3–254 characters; exactly one @; local part ≤ 64 and domain ≤ 255; no spaces or consecutive dots; matched case-insensitively
Password	At least 12 characters, including an uppercase letter, a digit, and a special character
Resource name (VM, network, firewall, subnet, role, account…)	3–64 characters; must start with a letter or number; letters, numbers, dots and dashes only (no spaces or underscores)	`^[A-Za-z0-9][A-Za-z0-9.-]{2,63}$`
Descriptive / loose name	1–255 characters; letters, numbers, dots, underscores, spaces and dashes	`^[A-Za-z0-9._\s-]+$`
Tag key	1–64 characters; start with a letter or number; letters, numbers, dot, underscore, hyphen	`^[a-zA-Z0-9][a-zA-Z0-9._-]{0,63}$`
Tag value	1–255 characters; letters, numbers and . _ : / space -	`^[a-zA-Z0-9._:/ -]+$`
Interface name	1–64 characters; letters, numbers, dot, underscore, hyphen	`^[a-zA-Z0-9._-]+$`
Hostname	Up to 253 characters; each label 1–63 characters; no leading or trailing hyphen (RFC 1123)

Networking values

Field	Allowed values
VLAN ID	1–4094
Port	1–65535
Port range	e.g. 80-443, or the keyword any
Firewall rule / NAT rank	1–9998
CIDR (network / subnet)	A valid IP with prefix where the host bits are zero, e.g. 10.0.0.0/24
IP or CIDR (rule match)	A single IP address, or an IP/prefix (host bits allowed)
WireGuard public key	44-character base64 ending in "=" (pattern ^[A-Za-z0-9+/]{43}=$)

Compute sizing

Field	Rule
vCPU	Whole number, at least 1
RAM	Whole number; minimum 512 MB
Disk size	Whole number of GB greater than 0, not exceeding the storage pool’s available capacity; can be increased later but never reduced

Fixed value sets

Field	Allowed values
VM importance	Low, Medium, High
Guest OS	windows, linux, other
Account status	active, inactive
Feature-request title	1–100 characters
Feature-request description	1–65,535 characters

These fixed ranges are the platform’s only hard limits. Everything else (CPU, memory, storage, counts) is governed by per-tenant quotas — see the Quotas reference (click here) — where 0 or unset means unlimited.
