RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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

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?

Comment 4 Radek Duda 2016-06-23 13:10:58 UTC 
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

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
