How do I reinstall a Hyper-V host without exporting/importing VMs?

-

i need reinstall host os least possible downtime vms?  from i've read, have shut down vm in order export it, , export process slow.  since vms include company exchange server , domain controller, need have little down time possible.

the host os on own partition, format/reinstall host on partition , leave vhds at.  i hope able install hyper-v on host , restart vms.  is possible?

thanks

hi!

exporting virtual machine hard drives (vhd files) takes time.

you can take @ ben armstrongs blogpost on how export/import configuration files only: http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/03/24/performing-a-configuration-only-export-import-on-hyper-v.aspx

since vhd files located on partition separated os, not need exported location , quicken export/import process significantly. also, try encourage take backups of vm's before modifying drives, in case.

you must export vm's first before importing them on newly installed system.
