Ok, I can reproduce it:
mount a drive as D: open a cmd.exe cd D:\ now unplug. the cmd.exe will block the acpi unplug, I have an explicit error message in windows event viewer: "cmd.exe stopped the removal or ejection for the device...." I don't think it's possible to force removal, as device_del wait for the ack of acpi unplug from guest. I'll try to do a drive_add if this occur, maybe it'll give us access again to drive. ----- Mail original ----- De: "Alexandre DERUMIER" <aderum...@odiso.com> À: "Martin Maurer" <mar...@proxmox.com> Cc: pve-devel@pve.proxmox.com Envoyé: Mardi 19 Février 2013 15:20:04 Objet: Re: [pve-devel] activate hotplug by default ? to be more exact >>1) drive_del (drive removal from controller = eject from windows) remove the block part, "info block" should show device removed >>2) device_del (remove the controller) "info pci" should see controller removed. I don't wait between 1) and 2), so maybe the bug is here. I'll investigate this afternoon. ----- Mail original ----- De: "Alexandre DERUMIER" <aderum...@odiso.com> À: "Martin Maurer" <mar...@proxmox.com> Cc: pve-devel@pve.proxmox.com Envoyé: Mardi 19 Février 2013 14:23:14 Objet: Re: [pve-devel] activate hotplug by default ? Hi Martin, The unplug works in 2 parts : 1) drive_del (drive removal from controller = eject from windows) 2) device_del (remove the controller) they are async, and I check the device list after removal a loop for 5 seconds. Can you post a "info pci" result from monitor after 1min by example, to see if the drive is not remove too late. What was the usage of the disk you remove ? (heavy read/write access ?)

As soon as I remove (hot-unplug) now a disk (e.g. from a win2008r2), I see the following error on the gui (after timeout): "error hot-unplug virtio2 at /usr/share/perl5/PVE/API2/Qemu.pm line 659. (500)" the monitor shows the disk as removed, the config is still with the disk and the windows box is on trouble (still shows the disk, but hang and display I/O device errors) It works, if I "eject" the disk inside windows before I remove it. As most user will just click remove (without eject it inside win), we will need to fix the problem and/or improve the user experience here. Any idea?
