[libvirt-users] usb post passthough stopped workng after kernel upgrade
Greetings, I have a vm on debian 9.5 to which I pass an specific usb from the host. here is the relevant part in the vm's xml file: the address line was added automatically by libvirt. everything was working well with kernel 4.15.11-1~bpo9+1 until I needed to upgrade the kernel to latest possible version due to usb issues I've upgraded to 4.18.6-1~bpo9+1. after the upgrade, my vm doesn't starts anymore, I see this msg: error: Failed to start domain router error: internal error: qemu unexpectedly closed the monitor: 2018-11-02T13:43:32.174730Z qemu-system-x86_64: -device usb-host,hostbus=1,hostaddr=4,id=hostdev4,bus=usb.0,port=1: failed to find host usb device 1:4 how can a kernel upgrade cause this? is there a fix for this issue?

But that depends what your area of interest is. Completers are small functions that are called from virsh whenever user started typing something and hit TAB TAB. Their purpose is to offer list of strings that suit entered input. If there is only one item on the list then it's entered in automatically. For instance: virsh # dom domblkerror domblkstat domcontrol domfsinfo .. virsh # start --domain fedora fedora.i686 freebsd gentoo ... (this will vary depending on your domains intalled) The framework is merged, the only thing that is missing are these small functions (called callbacks) that are called by the framework at appropriate times. For instance: virshDomainNameCompleter() is called whenever a domain name is to be completed (just like we've seen for virsh start example). I find writing completers to be a nice introduction into libvirt because they use our public APIs therefore one gets sense of libvirt. But feel free to chose anything, I'm just putting it out there.

We created a wiki page for this purpose [1] with small tasks which ought to help new contributors to get going and also get familiar with libvirt a bit more along the way.

Whic operation of "rebase" do you mean? Unfortunately we've implemented the virDomainBlockCopy API also using a flag-hack with the rebase api. Are you passing in VIR_DOMAIN_BLOCK_REBASE_COPY? If yes, then you in fact should use virDomainBlockCopy API which takes an XML which allows to specify also a network based disk. The support for block copy to a network destination will be added soon as I'm working on it. Without the VIR_DOMAIN_BLOCK_REBASE_COPY flag it should work as expected right now, since it pulls in changes from backing files. signature.asc Description: PGP signature ___ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users

This doesn't really sound like a libvirt issue, CCing spice list for investigation. Erik ___ libvirt-users mailing list libvirt-users@redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users
