Yeah, it's very likely that any API that calls to qemu-ga is affected. I'll check all of them...
This issue is now fixed upstream by v0.10.0-10-ge360a96 and v0.10.0-11-g7444ccc: commit 7444ccce4cb4af1ce61eb4c2c9ce4f69ea276e9c Author: Jiri Denemark <jdenemar@redhat.com> Date: Thu Aug 30 14:40:01 2012 +0200 qemu: Revert to blocking behavior of qemuAgentCommand Before commit 05447e3af44ec153314ff97cd611330d9b4b5730, qemuAgentCommand blocked until it got a reply or appropriate event. When new parameter was added to qemuAgentCommand in the above commit, all existing callers of it were updated in a wrong way changing them from blocking to 5-seconds timeout. commit e360a96067c685d53d5c32c912db14520acdb089 Author: Jiri Denemark <jdenemar@redhat.com> Date: Thu Aug 30 14:19:02 2012 +0200 qemu: Remove redundant parameter from qemuAgentSend The @timeout parameter of qemuAgentSend is both redundant and confusing. This patch should not result in any functional changes.
