Shared VM Templates for Hyper-V
Hyper-V has no built-in template sharing. eryph adds a template library with downloadable base VMs and team configurations.
Every Hyper-V team struggles with template sharing
No central library means duplicate work everywhere
Dev Teams
85 min clones
Eager-zeroed disks
IT Departments
No template library
Manual distribution
MSP Provider
Template per client
Maintenance nightmare
Training Centers
Instructor templates
Not shareable

The Pattern
Every organization hits the same wall: Manual VM provisioning doesn't scale. What starts as "just a few VMs" becomes a full-time job, blocking your team from actual work.
Ready to move beyond golden images?
Modern VM management without sysprep
Hyper-V template limitations
Why traditional Hyper-V templates hit a wall with complex environments
Static Templates Only
Golden images are fixed snapshots, can't be composed or extended
→ Limited reusability
No Template Hierarchy
Can't build one template from another
→ Duplicate base configurations
Manual Golden Image Updates
Must rebuild entire image for any change
→ Time-consuming maintenance
No Configuration Inheritance
Each template contains full OS + app configuration
→ Large, monolithic images
Template Sprawl
Need separate golden image for each environment type
→ Storage and management overhead
Static Templates Only
Golden images are fixed snapshots, can't be composed or extended
→ Limited reusability
eryph enables true template sharing
Download base VMs from genepool, add your configs, share with your team
Hyper-V Alone
- ✗No template library
- ✗Manual VHDX copying
- ✗Settings lost in transfer
- ✗No versioning
- ✗Can't build on others' work
- ✗IT bottleneck (SCVMM admin-only)
Hyper-V + eryph
- Central genepool library
- Download base catlets instantly
- Configuration travels with VM
- Full Git versioning
- Inherit and extend templates
- Everyone can share (not just IT)

How the gene system works
1. Start with a gene
Choose a proven template from the genepool or create your own
2. Add what's different
Inherit base configs, customize only what you need
3. Deploy in minutes
Your improvements become new genes others can inherit
Real example: Deploy an Ubuntu web server from YAML
# Deploy Ubuntu web server from YAML:
# Perfect for dev, test, and staging workloads
$webServer = @"
name: web-server-01
parent: dbosoft/ubuntu-2204/latest
# Configure web server stack
fodder:
- source: gene:myorg/ubuntu-nginx-base
variables:
- name: site_name
value: myapp.local
"@
# Deploy it
New-Catlet -Config $webServer | Start-Catlet
# Done! Ubuntu web server ready in minutes.
