Storage Management

  • Place VHDs on separate spindles
  • Use fixed VHDs for production
  • Regularly compact dynamic disks
  • Monitor disk performance
  • Implement Storage QoS
  • Plan for growth

Network Configuration

  • Use separate NICs for management
  • Implement NIC teaming
  • Configure VLANs appropriately
  • Enable SR-IOV when available
  • Monitor network performance
  • Document network topology

Security Hardening

  • Enable Secure Boot
  • Use TPM for encryption
  • Implement Shielded VMs
  • Regular patching schedule
  • Role-based access control
  • Audit logging enabled

Automation and Scripting

PowerShell Automation Examples

# Daily VM backup script
$VMs = Get-VM | Where-Object {$_.State -eq 'Running'}
foreach ($VM in $VMs) {
    Export-VM -Name $VM.Name -Path "E:\Backups\$(Get-Date -Format 'yyyy-MM-dd')"
}

# Resource monitoring script
Get-VM | Select-Object Name,
    @{N='CPU(%)';E={$_.CPUUsage}},
    @{N='Memory(GB)';E={[math]::Round($_.MemoryAssigned/1GB,2)}},
    State | Export-Csv "C:\Reports\VM-Status.csv"

# Automated VM provisioning
function New-StandardVM {
    param($VMName, $Memory, $CPUs)

    New-VM -Name $VMName -Generation 2 -MemoryStartupBytes $Memory
    Set-VM -Name $VMName -ProcessorCount $CPUs -DynamicMemory
    Add-VMNetworkAdapter -VMName $VMName -SwitchName "Production"
    New-VHD -Path "D:\VMs\$VMName\$VMName.vhdx" -SizeBytes 80GB
    Add-VMHardDiskDrive -VMName $VMName -Path "D:\VMs\$VMName\$VMName.vhdx"
}

# Health check script
$Report = @()
foreach ($VM in Get-VM) {
    $Report += [PSCustomObject]@{
        Name = $VM.Name
        State = $VM.State
        CPUUsage = $VM.CPUUsage
        MemoryGB = [math]::Round($VM.MemoryAssigned/1GB,2)
        IntegrationServices = $VM.IntegrationServicesState
        Uptime = $VM.Uptime
    }
}
$Report | ConvertTo-Html | Out-File "C:\Reports\Health.html"

Remote Management

Enable Remote Management
# Enable PowerShell Remoting
Enable-PSRemoting -Force

# Configure WinRM
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force

# Connect to remote Hyper-V host
Enter-PSSession -ComputerName "HyperV-Host01"

# Run commands on remote host
Invoke-Command -ComputerName "HyperV-Host01" -ScriptBlock {
    Get-VM | Select-Object Name, State
}

Capacity Planning

CPU Planning

  • Monitor CPU utilization trends
  • Typical overcommit: 2:1 to 4:1
  • Leave 20% buffer for spikes
  • Consider workload patterns
  • Plan for maintenance windows

Memory Planning

  • Reserve memory for host OS
  • Dynamic Memory reduces needs
  • Monitor memory pressure
  • Plan for VM growth
  • Consider NUMA boundaries

Storage Planning

  • Calculate IOPS requirements
  • Plan for snapshot overhead
  • Consider backup storage
  • Monitor disk queue length
  • Plan for 20-30% growth

Network Planning

  • Separate traffic types
  • Calculate bandwidth needs
  • Plan for Live Migration
  • Consider storage traffic
  • Implement redundancy

Troubleshooting Common Issues

Issue Potential Causes Resolution Steps
VM Won't Start Insufficient resources, disk issues Check event logs, verify disk space, check memory availability
Slow Performance Resource contention, storage bottleneck Monitor PerfMon counters, check disk I/O, review CPU/memory
Network Issues Virtual switch configuration, NIC teaming Verify switch settings, check physical NIC, test connectivity
Live Migration Fails Authentication, network, compatibility Verify Kerberos/CredSSP, check network paths, validate versions
Checkpoints Not Working VSS issues, disk space Check VSS service, verify disk space, review event logs

Patch Management

Hyper-V Update Strategy

  1. Plan Maintenance Window: Schedule during low-usage periods
  2. Backup VMs: Create checkpoints or backups before updates
  3. Test Updates: Deploy to test environment first
  4. Live Migrate VMs: Move VMs to other hosts if clustering
  5. Install Updates: Use Windows Update or WSUS
  6. Restart Host: Reboot after updates complete
  7. Verify Operation: Check VMs, services, and performance
  8. Update Guests: Patch guest VMs on schedule

Licensing Considerations

Windows Server Licensing

  • Standard Edition: Licenses 2 VMs (or 2 Hyper-V containers) per license
  • Datacenter Edition: Unlimited VMs on licensed host
  • Core-Based Licensing: Minimum 16 cores per server
  • Guest OS Licensing: Separate licenses required for Windows guest VMs
  • Azure Hybrid Benefit: Use on-premises licenses in Azure

Documentation and Compliance

Required Documentation

  • Network topology diagrams
  • VM inventory and specifications
  • Storage allocation maps
  • Backup and DR procedures
  • Change management logs
  • Security configurations

Compliance Requirements

  • Audit logging enabled
  • Access control documentation
  • Encryption at rest and transit
  • Regular vulnerability scans
  • Patch compliance tracking
  • Incident response procedures
