| - | ==== (Optional) Preparation ==== | ||
| - | Cleanup disc space and remove all unnecessary drivers: | ||
| - | * uninstall Virtual Box Guest Additions | ||
| - | * Download and run registry file: [[https://pve.proxmox.com/wiki/File:Mergeide.zip|Mergeide.zip]] | ||
| - | * Restart VM | ||
| - | * ''sdelete -z c: d: e:'' | ||
| - | * Enable ''ClearPageFileAtShutdown.reg'' | ||
| - | * Shutdown VM | ||
| - | Now two methods are possible: | ||
| ==== DRAFT ==== | ==== DRAFT ==== | ||

| - | ==== Importing only disc ==== | ||
| - | Fastest method: create Proxmox machine and import vbox hard disc to newly created Proxmox VM. | ||
| - | * Create new Proxmox machine with similar parameters to old one | ||
| - | * [[https://pve.proxmox.com/wiki/Windows_10_guest_best_practices|Windows 10 guest best practices]] | ||
| - | * Remove created Hard Disc (scsi0) | ||
| - | * Import disc images (repeat for all VDI discs) | ||
| - | * As RAW images with all benefits (compression, thin provisioning, snapshots) of ''local-zfs'' storage: <code bash>qm importdisk 701 WIN7_C.vdi local-zfs</code> | ||
| - | * 21743 MB VDI compacted file occupied 15,2G on ZFS with compression ratio 1.24x | ||
| - | * As QCOW2 files on every file storage: <code bash>qm importdisk 701 WIN7_C.vdi local -format qcow2</code> | ||
| - | * Connect new discs into machine: | ||
| - | * <code bash>qm set 701 --scsi<N> local-zfs:vm-701-disk-<N>,cache=writeback,discard=on,size=64G</code> | ||
| - | * NOTE: ''discard=on'' should be enabled for thin provisioned storage to reclaim unused space | ||
| - | * Switch SCSI to IDE: <code bash>sed -i 's/scsi/ide/g' /etc/pve/qemu-server/701.conf</code> | ||
| - | * Manually correct numbering conflict with CD-ROM ide drive | ||
| - | * Setup correct boot order | ||
| - | * Add one dummy (small size) hard disc to SCSI controller | ||
| - | * Enable QEMU Guest Agent | ||
| - | * Boot Windows, go to ''Device Manager'' and install missing drivers: | ||
| - | * PCI Simple Communication Controller ''PCI\VEN1AF4&DEV_1003'' --> Virtio console ''vioserial'' | ||
| - | * Red Hat VirtIO SCSI pass-through controller ''vioscsi\w7\amd64'' | ||
| - | * ''NetKVM\w7\amd64'' | ||
| - | * (''PCI\VEN_1AF4&DEV_1002'') --> VirtIO Balloon Driver ''Balloon\w7\amd64'' | ||
| - | * vm generation id (''ACPI/QEMUVGID'') '''' | ||
| - | * Shutdown machine | ||
| - | * Switch disc controller from IDE to SCSI. Edit ''/etc/pve/qemu-server/701.conf'' | ||
| - | * Setup correct boot order | ||
| - | |||
| - | sed -i 's/ide/scsi/g' /etc/pve/qemu-server/701.conf | ||
| - | |||
| - | ==== NOT WORKING: Importing OVA file ==== | ||
| - | * **Very slow method**, exporting OVA needs to copy all discs into exported and well compressed file. | ||
| - | * In VirtualBox choose "**File**" --> **"Export Appliance"** | ||
| - | * select to export all network cards and MAC addresses | ||
| - | * Proxmox cannot import OVA files directly. Please unpack it with command <code bash>tar -xvf WIN7.ova</code> | ||
| - | * After unpacking, manifest file .ovf will be available. | ||
| - | * <code bash>qm importovf 701 ./WIN7.ovf local-zfs --dryrun --format qcow2</code> | ||
| - | * WARNING: <code>warning: unable to parse the VM name in this OVF manifest, generating a default value</code> | ||
| - | * Create account/Login to VMWare page and download [[https://my.vmware.com/group/vmware/get-download?downloadGroup=OVFTOOL440|ovftool]] | ||
