[Bug 258771] Re: Using -usbdevice host: slows the guest OS down to a crawl
As per https://wiki.ubuntu.com/VirtFeatureVerification, I did not see this problem when testing USB with lucid and maverick. Certainly data transfer could be slow, but I never saw a slowdown of the guest OS. Can you confirm whether you can still reproduce this? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to kvm in Ubuntu. https://bugs.launchpad.net/bugs/258771 Title: Using -usbdevice host: slows the guest OS down to a crawl To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kvm/+bug/258771/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I don't have the device handy to try to reconfirm the original issue, so let's leave it closed for now. If the problem turns up again, hopefully this bug will be found again. -- - mdz -- Using -usbdevice host: slows the guest OS down to a crawl https://bugs.launchpad.net/bugs/258771 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

If not, it's hard to tell whether the problem is fixed, or if your case didn't trigger it. One hint from the original report was that the device in question had multiple interfaces.

[Bug 258771] Re: Using -usbdevice host: slows the guest OS down to a crawl
Hi Matt- I actually believe this bug to be fixed in Lucid's qemu-kvm 0.12.3. Similar to your original report, I fired up a VM with usb attached to my Palm Pre phone, which can act as a USB dongle. I was able to successfully connect to the internet in the VM with: $ sudo kvm -m 512 -hda testdrive-disk-nMLT3b.img -usb -usbdevice host:0830:0101 usb_create: no bus specified, using "usb.0" for "usb-host" husb: open device 2.7 husb: config #5 need -1 husb: 4 interfaces claimed for configuration 5 husb: grabbed usb device 2.7 husb: config #5 need 5 husb: 4 interfaces claimed for configuration 5 husb: config #5 need 5 husb: 4 interfaces claimed for configuration 5 husb: config #5 need 5 husb: 4 interfaces claimed for configuration 5 husb: config #5 need 5 husb: 4 interfaces claimed for configuration 5 And in the guest, it was able to connect through the dongle to the internet. There was no noticeable degradation in performance in either the host or guest. Screenshot attached.

[Bug 258771] Re: Using -usbdevice host: slows the guest OS down to a crawl
Some USB devices have higher polling frequencies than others. An abnormally high polling frequency could easily cause a guest to crawl to a halt. Also, it could be that your device is a USB 2.0 device that is falling back to USB 1.1 in the guest, which could also slow things down considerably. Otherwise, this could be an issue in the kernel's USB code. None of these are solutions to the bug, but I'm trying to capture a few ideas... :-Dustin ** Changed in: kvm (Ubuntu) Status: Incomplete => Won't Fix ** Changed in: qemu (Ubuntu) Status: New => Won't Fix ** Also affects: qemu-kvm (Ubuntu) Importance: Undecided Status: New ** Changed in: qemu-kvm (Ubuntu) Status: New => Incomplete ** Changed in: qemu-kvm (Ubuntu) Importance: Undecided => Low -- Using -usbdevice host: slows the guest OS down to a crawl https://bugs.launchpad.net/bugs/258771 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Marking won't fix against qemu and kvm, which no longer exist in Ubuntu. Marking incomplete against qemu-kvm in karmic. If this is still an issue, please confirm it there.
