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.

Fixed In Version: spice-server-0.7.2-2.el6
Doc Type: Bug Fix
Doc Text:
Note to Content Author: I think this was not seen by users, but was part of developing spice-server and guest's vdagent. This bug adds a few fixes to the server, including: - Don't crash when a client disconnects while there are pending writes. - Always call read_from_vdi_port() in a while loop. This fixes a case where data read from the agent got lost. - Call read_from_vdi_port() from vdi_read_buf_release(). This fixes a possible case where spice-server fails to ever read more data from the agent on the guest as the port is throttled and stays throttled until the spice-server consumed all data from the current buffer.

Description Hans de Goede 2010-10-20 20:02:39 UTC 
With the enabling of copy and paste support in RHEV-2.3, there will be a lot more data flowing through the vdagent channel. This means that we need to look at backporting the following upstream commits, which fix some issues in the server wrt vdagent channel data handling:

Verified by code review of spice-server-0.8.0-1 patches seems to be implemented.
