I've tested this combined with Spice seamless migration, and it can successful: 1) migrate a vm while running "dd if=/dev/zero of=/dev/sdb1 bs=32K" inside the guest with sdb being a redirect USB-2 mass storage device. 2) migrate a vm while running camorama inside the vm showing a 720p video from a redirected USB-2 webcam at 30 fps! Note this is based on usb-next rather then master / usb.62, since one of my patches would otherwise conflict with your recent ehci changes. Changes in v2: - As discussed drop the "usb: Migrate over device speed and speedmask" patch The following changes since commit a44fd2e0c66b2276f586948702e5ebc7136fdb73: usb-host: allow emulated (non-async) control requests without USBPacket (2012-09-06 12:03:41 +0200) are available in the git repository at: git://people.freedesktop.org/~jwrdegoede/qemu usb-for-gerd for you to fetch changes up to 6ef0b771704ca898a44c1f9ea41ab98590fc2e84: usb-redir: Add chardev open / close debug logging (2012-09-07 21:27:16 +0200) ---------------------------------------------------------------- Hans de Goede (8): ehci: Don't set seen to 0 when removing unseen queue-heads ehci: Walk async schedule before and after migration ehci: Don't process too much frames in 1 timer tick usb-redir: Change cancelled packet code into a generic packet-id queue usb-redir: Add an already_in_flight packet-id queue usb-redir: Store max_packet_size in endp_data usb-redir: Add support for migration usb-redir: Add chardev open / close debug logging hw/usb/hcd-ehci.c | 61 ++++++- hw/usb/redirect.c | 500 ++++++++++++++++++++++++++++++++++++++++++++++++++---- 2 files changed, 522 insertions(+), 39 deletions(-) Thanks & Regards, Hans
