I tried with qemu-kvm-1.5.3-30.el7 which should be identical to qemu-kvm-rhev. Closing after failing to reproduce w/qemu-kvm-1.5.3-52.el7.x86_64 on a RHEL-7 host. win8.1-32 guest still hit this issue on rhel7 host: steps same as comment#0 actual result: no warning message shown in qemu monitor during hotplug/hotunplug,but still only one port can be seen in guest; after reboot guest,two ports can be detected and neither of them can work normally. expected result: after the unplug/plug loop,two ports can work correctly package infoļ¼ kernel-3.10.0-110.el7.x86_64 qemu-kvm-rhev-1.5.3-53.el7.x86_64 seabios-1.7.2.2-12.el7.x86_64 virtio-win-prewhql-75 Does it reproduce on qemu-kvm-1.5.3-52.el7.x86_64 (non rhev version)? Thanks. (In reply to Gal Hammer from comment #8) > Does it reproduce on qemu-kvm-1.5.3-52.el7.x86_64 (non rhev version)? Thanks. Yes,I can reproduce this issue with qemu-kvm-1.5.3-53.el7.x86_64 test with virtio-win-prewhql-90 and qemu-kvm-0.12.1.2-2.441.el6.bz1027181.x86_64: steps as comment#0,virtserialort can be hot-unplug/hot-plug correctly,and after the loop ends,virtserialport can work well. package info: qemu-kvm-0.12.1.2-2.441.el6.bz1027181.x86_64 virtio-win-prewhql-90 2.6.32-486.el6.x86_64 Hi Mike, Based on comment #13, can we close this one? Second, is this a duplicate of bug 1044341 (or vice verse)? Thanks, Gal. (In reply to Gal Hammer from comment #14) > Hi Mike, > > Based on comment #13, can we close this one? We can not close it as fixed we are using stratch build on #13. As Amit claims 1043403 originally is a RHEL7 bug. The fix in bug 1027181 is targeted for RHEL6. RHEL7 already has the fix mentioned there. I think both of the 2 bugs may close as dup of 1043403 after it fixed. What's your idea ?

Keep just one open for tracking and close the rest as dups. No need to wait for a fix. > Thanks, > Mike Closing as DUPLICATED based on comment #13. *** This bug has been marked as a duplicate of bug 1027181 *** |
