In qemu-kvm-rhev-2.1.2-1.el7.x86_64, it's enable to create image filename containing a ':', but in qemu-kvm-rhev-2.3.0-13.el7.x86_64 it is unable to create such filename. So this bug is a regression.

Hi,

Both notations work for me in qemu-kvm-rhev-2.3.0-13.el7:

First one (./foo:bar):

$ ./qemu-img create ./foo:bar.qcow2 64M
Formatting './foo:bar.qcow2', fmt=qcow2 size=67108864 encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16
$ ls -l foo:bar.qcow2
-rw-r--r-- 1 mreitz users 197120 31. Jul 14:52 foo:bar.qcow2
$ ./qemu-img info ./foo:bar.qcow2
image: ./foo:bar.qcow2
file format: qcow2
virtual size: 64M (67108864 bytes)
...

Second one (file:foo:bar, the one that was fixed for BZ 1071058):

$ ./qemu-img create -f qcow2 file:foo:bar.qcow2 64M     
Formatting 'file:foo:bar.qcow2', fmt=qcow2 size=67108864 encryption=off cluster_size=65536 lazy_refcounts=off refcount_bits=16
$ ls -l foo:bar.qcow2
-rw-r--r-- 1 mreitz users 197120 31. Jul 14:56 foo:bar.qcow2
$ ./qemu-img info file:foo:bar.qcow2
image: foo:bar.qcow2
file format: qcow2
virtual size: 64M (67108864 bytes)
...

Note that "foo:bar.qcow2" not working is intentional (see BZ 1071058 comment 7).

So both seem to work for me.

Hi Max,

I am sorry for missing BZ 1071058 comment 7 before. I re-tested with './ip-192.168.254.185:asdf' and 'file:ip-192.168.254.186:asdf', and both file names work.

So this bug is not a bug.


Thanks,
zhangpei
