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.

Description Shaolong Hu 2015-01-23 07:19:50 UTC 
Description of problem:
-------------------------
QMP drive_mirror command with "format":"raw" hang


Version-Release number of selected component (if applicable):
---------------------------------------------------------------
qemu-kvm-rhev-2.1.2-20.el7.x86_64


How reproducible:
------------------
100%


Steps to Reproduce:
---------------------
1. boot guest, do drive_mirror with target format RAW:

{ "execute": "drive-mirror", "arguments": { "device": "drive-virtio-disk0", "target": "/home/sn1", "format": "raw", "mode": "absolute-paths", "sync": "full", "speed": 1000000000, "on-source-error": "stop", "on-target-error": "stop" }

2. after step 1, command hangs, no return.


CMD:
/usr/libexec/qemu-kvm -enable-kvm -M pc-i440fx-rhel7.0.0 -smp 4 -m 4G -name rhel6.3-64 -uuid 3f2ea5cd-3d29-48ff-aab2-23df1b6ae213 -drive file=/home/RHEL-Server-7.1-64-virtio.raw,cache=none,if=none,rerror=stop,werror=stop,id=drive-virtio-disk0,format=raw,aio=native -device virtio-blk-pci,drive=drive-virtio-disk0,id=device-virtio-disk0,bootindex=1 -boot order=cd -monitor stdio -readconfig nfs/ich9-ehci-uhci.cfg -device usb-tablet,id=input0 -chardev socket,id=s1,path=/tmp/s1,server,nowait -device isa-serial,chardev=s1 -monitor tcp::1235,server,nowait -vga qxl -global qxl-vga.revision=3 -spice port=5930,disable-ticketing -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -vnc :10 -qmp tcp:0:5555,server,nowait -sandbox on -cpu host -netdev tap,script=/etc/qemu-ifup,id=netdev0 -device virtio-net-pci,netdev=netdev0,id=device-net0,mac=aa:54:00:11:22:33



Additional info:
-------------------
1. HMP command works correctly
2. If not specify "format": "raw", this leaves target format kept same with source, in this case: RAW, this also works fine.
