Hey, if server crashed, what are the server logs ? See also the bug 1338752 which is related to server/guest issues after disconnection of usb device (In reply to Radek Duda from comment #0) > Steps to Reproduce: > 1.Boot guest VM > 2.Redirect USB device connected to client > 3.detach USB device from client machine without any redirection > > Actual results: > guest VM crashes with error: > (remote-viewer:12225): GSpice-CRITICAL **: usbredirhost: error resetting > device: LIBUSB_ERROR_NO_DEVICE > This is an error/warning from the client. Could you try to provide with a backtrace of the client if it crashes, or of qemu if it's really the guest that crahses. thanks? Created attachment 1171492 [details]
qemu-kvm backtrace
Pavel, I found the bug 1338752 to be very similar. The USB device does not have to be detached rudely,but even when detaching with remote-viewer redirection the guest crashes. To server log right after USB detachment are added these lines: qemu-kvm: spice-qemu-char.c:188: spice_chr_write: Assertion `s->datalen == 0' failed. 2016-06-23 12:58:38.689+0000: shutting down versions of used components: # rpm -q usbredir qemu-kvm kernel libvirt usbredir-0.7.1-1.el7.x86_64 qemu-kvm-1.5.3-115.el7.x86_64 kernel-3.10.0-445.el7.x86_64 libvirt-1.3.5-1.el7.x86_64 $ rpm -qa | grep spice spice-glib-0.31-3.el7.x86_64 spice-gtk3-0.31-3.el7.x86_64 spice-protocol-0.12.11-1.el7.noarch spice-gtk-0.31-3.el7.x86_64 spice-server-0.12.4-17.el7.x86_64 spice-gtk-tools-0.31-3.el7.x86_64 spice-vdagent-0.14.0-13.el7.x86_64 the crash is in qemu-kvm. The backtrace is attached. The reproducer, result and the backtrace are similar as in the bug 1338752, closing as duplicate *** This bug has been marked as a duplicate of bug 1338752 *** |
