Hi, a quick question - was curious if anyone can comment on current status:experience for this:
In the past I had tried to setup USB passthrough on a KVM based windows server 2003 VM running on ProxVE 1.8 or so (ie, that was the latest-current version at the time of ProxVE). The idea was to use the USB drive as a backup storage target which could easily be taken offsite / as part of a rotating pool of USB drives for making basic backups (once weekly full with incrementals all other nights; rotating the drives once per week)
At the time, the general endgame of the test: USB passthrough was "OK" for low-data-intensity stuff like USB security dongles (ie hardware license dongle) but less good for anything that did more serious data transfer (ie, hard drive running 'saturated USB data transfer connection'). In general the outcome was that the USB drive was visible via passthrough to the guest OS, but that any significant data transfer (ie, more than a few megs) would result in hard panic crash of the KVM guest. It may even have blown up the entire ProxVE host/kernel; I forget. (alas my memory when I don't write things down!)
Anyhow. Just curious if things have changed in the last ~year or more / and with the release of ProxVE 2.X series / and presuably we are on newer versions of KVM which might have changed behaviour.
Many thanks for any commentsbservations:real world use stories
