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.

Comment 9 dehanmeng 2021-02-06 08:13:23 UTC 
Verify with version qemu-kvm-4.2.0-34.module+el8.3.0+9828+7aab3355.3
Steps to Reproduce:

1.Start guest with virtio serial and start guest agent inside the guest and add two disks.
2.execute guest-get-disks in the unix socked, but there are some test situation like following items:
[root@dell-per440-06 qemu-kvm]# nc -U /tmp/helloworld2
{"execute":"guest-ping"}
{"return": {}}
{"execute":"guest-ping"}
{"return": {}}
{"execute":"guest-info"}
{"return": {"version": "4.2.0", "supported_commands": [{"enabled": true, "name": "guest-get-osinfo", "success-response": true}, {"enabled": true, "name": "guest-get-timezone", "success-response": true}, {"enabled": true, "name": "guest-get-users", "success-response": true}, {"enabled": true, "name": "guest-get-host-name", "success-response": true}, {"enabled": false, "name": "guest-exec", "success-response": true}, {"enabled": false, "name": "guest-exec-status", "success-response": true}, {"enabled": true, "name": "guest-get-memory-block-info", "success-response": true}, {"enabled": true, "name": "guest-set-memory-blocks", "success-response": true}, {"enabled": true, "name": "guest-get-memory-blocks", "success-response": true}, {"enabled": true, "name": "guest-set-user-password", "success-response": true}, {"enabled": true, "name": "guest-get-fsinfo", "success-response": true}, {"enabled": true, "name": "guest-get-disks", "success-response": true},  ...
{"execute":"guest-get-disks"}
{"return": [{"name": "/dev/vda", "dependencies": [], "partition": false, "address": {"bus-type": "virtio", "bus": 0, "unit": 0, "pci-controller": {"bus": 0, "slot": 6, "domain": 0, "function": 0}, "dev": "/dev/vda", "target": 0}}, {"name": "/dev/sda", "dependencies": [], "partition": false, "address": {"serial": "0QEMU_QEMU_HARDDISK_kk", "bus-type": "scsi", "bus": 0, "unit": 0, "pci-controller": {"bus": 4, "slot": 0, "domain": 0, "function": 0}, "dev": "/dev/sda", "target": 0}}, {"name": "/dev/dm-0", "dependencies": ["/dev/vdb2"], "partition": false, "alias": "rhel_bootp--73--75--166-root"}, {"name": "/dev/vdb1", "dependencies": ["/dev/vdb"], "partition": true}, {"name": "/dev/vdb2", "dependencies": ["/dev/vdb"], "partition": true}, {"name": "/dev/vdb", "dependencies": [], "partition": false, "address": {"bus-type": "virtio", "bus": 0, "unit": 0, "pci-controller": {"bus": 2, "slot": 0, "domain": 0, "function": 0}, "dev": "/dev/vdb", "target": 0}}, {"name": "/dev/dm-1", "dependencies": ["/dev/vdb2"], "partition": false, "alias": "rhel_bootp--73--75--166-swap"}]}

Check on guest:
NAME                             MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda                                8:0    0  20G  0 disk
vda                              252:0    0  20G  0 disk
vdb                              252:16   0  20G  0 disk

  ├─rhel_bootp--73--75--166-root 253:0    0  17G  0 lvm  /
  └─rhel_bootp--73--75--166-swap 253:1    0   2G  0 lvm  [SWAP]

3. Partition, format and mount one of the disks, check info:
{"execute":"guest-get-disks"}
{"return": [{"name": "/dev/vda", "dependencies": [], "partition": false, "address": {"bus-type": "virtio", "bus": 0, "unit": 0, "pci-controller": {"bus": 0, "slot": 6, "domain": 0, "function": 0}, "dev": "/dev/vda", "target": 0}}, {"name": "/dev/sda1", "dependencies": ["/dev/sda"], "partition": true}, {"name": "/dev/sda", "dependencies": [], "partition": false, "address": {"serial": "0QEMU_QEMU_HARDDISK_kk", "bus-type": "scsi", "bus": 0, "unit": 0, "pci-controller": {"bus": 4, "slot": 0, "domain": 0, "function": 0}, "dev": "/dev/sda", "target": 0}}, {"name": "/dev/dm-0", "dependencies": ["/dev/vdb2"], "partition": false, "alias": "rhel_bootp--73--75--166-root"}, {"name": "/dev/vdb1", "dependencies": ["/dev/vdb"], "partition": true}, {"name": "/dev/vdb2", "dependencies": ["/dev/vdb"], "partition": true}, {"name": "/dev/vdb", "dependencies": [], "partition": false, "address": {"bus-type": "virtio", "bus": 0, "unit": 0, "pci-controller": {"bus": 2, "slot": 0, "domain": 0, "function": 0}, "dev": "/dev/vdb", "target": 0}}, {"name": "/dev/dm-1", "dependencies": ["/dev/vdb2"], "partition": false, "alias": "rhel_bootp--73--75--166-swap"}]
Check on guest:
NAME                             MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda                                8:0    0  20G  0 disk
└─sda1                             8:1    0  20G  0 part /mnt/sda1
vda                              252:0    0  20G  0 disk
vdb                              252:16   0  20G  0 disk

  └─rhel_bootp--73--75--166-swap 253:1    0   2G  0 lvm  [SWAP]

4. umount in guest and check disks info
{"execute":"guest-get-disks"}
{"return": [{"name": "/dev/vda", "dependencies": [], "partition": false, "address": {"bus-type": "virtio", "bus": 0, "unit": 0, "pci-controller": {"bus": 0, "slot": 6, "domain": 0, "function": 0}, "dev": "/dev/vda", "target": 0}}, {"name": "/dev/sda1", "dependencies": ["/dev/sda"], "partition": true}, {"name": "/dev/sda", "dependencies": [], "partition": false, "address": {"serial": "0QEMU_QEMU_HARDDISK_kk", "bus-type": "scsi", "bus": 0, "unit": 0, "pci-controller": {"bus": 4, "slot": 0, "domain": 0, "function": 0}, "dev": "/dev/sda", "target": 0}}, {"name": "/dev/dm-0", "dependencies": ["/dev/vdb2"], "partition": false, "alias": "rhel_bootp--73--75--166-root"}, {"name": "/dev/vdb1", "dependencies": ["/dev/vdb"], "partition": true}, {"name": "/dev/vdb2", "dependencies": ["/dev/vdb"], "partition": true}, {"name": "/dev/vdb", "dependencies": [], "partition": false, "address": {"bus-type": "virtio", "bus": 0, "unit": 0, "pci-controller": {"bus": 2, "slot": 0, "domain": 0, "function": 0}, "dev": "/dev/vdb", "target": 0}}, {"name": "/dev/dm-1", "dependencies": ["/dev/vdb2"], "partition": false, "alias": "rhel_bootp--73--75--166-swap"}]}

Check on guest:
NAME                             MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda                                8:0    0  20G  0 disk
vda                              252:0    0  20G  0 disk
vdb                              252:16   0  20G  0 disk
├─vdb1                           252:17   0   1G  0 part /boot
└─vdb2                           252:18   0  19G  0 part
  ├─rhel_bootp--73--75--166-root 253:0    0  17G  0 lvm  /
  └─rhel_bootp--73--75--166-swap 253:1    0   2G  0 lvm  [SWAP]

5) delete one disk in guest and check disks info:
{"execute":"guest-get-disks"}
{"return": [{"name": "/dev/vda1", "dependencies": ["/dev/vda"], "partition": true}, {"name": "/dev/vda2", "dependencies": ["/dev/vda"], "partition": true}, {"name": "/dev/vda", "dependencies": [], "partition": false, "address": {"bus-type": "virtio", "bus": 0, "unit": 0, "pci-controller": {"bus": 2, "slot": 0, "domain": 0, "function": 0}, "dev": "/dev/vda", "target": 0}}, {"name": "/dev/sda1", "dependencies": ["/dev/sda"], "partition": true}, {"name": "/dev/sda", "dependencies": [], "partition": false, "address": {"serial": "0QEMU_QEMU_HARDDISK_kk", "bus-type": "scsi", "bus": 0, "unit": 0, "pci-controller": {"bus": 4, "slot": 0, "domain": 0, "function": 0}, "dev": "/dev/sda", "target": 0}}, {"name": "/dev/dm-0", "dependencies": ["/dev/vda2"], "partition": false, "alias": "rhel_bootp--73--75--166-root"}, {"name": "/dev/dm-1", "dependencies": ["/dev/vda2"], "partition": false, "alias": "rhel_bootp--73--75--166-swap"}]}

Check on guest:
AME                             MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda                                8:0    0  20G  0 disk
