[Qemu-devel] [Bug 1814420] [NEW] drive-backup with iscsi, it will failed "Could not create image: Invalid argument"

[Cheng Chen]

Public bug reported:

I use iscsi protocol to drive-backup:

---iscsi target---
yum -y install targetcli python-rtslib
systemctl start target
systemctl enable target
targetcli /iscsi create iqn.2019-01.com.iaas
targetcli /iscsi/iqn.2019-01.com.iaas/tpg1 set attribute authentication=0 demo_mode_write_protect=0 generate_node_acls=1
targetcli /iscsi/iqn.2019-01.com.iaas/tpg1/portals create 192.168.1.1 3260
targetcli /backstores/fileio create file1 /opt/file1 2G
targetcli /iscsi/iqn.2019-01.com.iaas/tpg1/luns create /backstores/fileio/file1
-------------------

Now, '{ "execute" : "drive-backup" , "arguments" : { "device" : "drive-
virtio-disk0" , "sync" : "top" , "target" :
"iscsi://192.168.1.1:3260/iqn.2019-01.com.iaas/0" } }'

It may failed:
{"id":"libvirt-1785","error":{"class":"GenericError","desc":"Could not
create image: Invalid argument"}}

But, This abnormal will be appear at the first time. Because when I
retry again, It works very well.

Then, I re-start the vm, It still be failed 'Could not create image:
Invalid argument' on the first try, and the second try it will work very
well.

[Bug 1814420] Re: drive-backup with iscsi, it will failed "Could not create image: Invalid argument"

[John Snow]

Hi, qemu version 3.1 is a bit old in terms of upstream support. Can you
confirm that this is still an issue on 4.2 ?
