Fixed In Version: rhv-guest-tools-iso-4.3-13
Doc Type: Bug Fix
Doc Text:
Previously, installing guest agents for Windows guests from rhv-guest-tools-iso-4.3-12.el7ev using rhev-apt.exe failed because it could not verify a filename that exceeded Windows' 63-character limit. The current release fixes this issue. It renames the file with a shorter name, so the installation process works.

Lev I know the recent development on the 4.3 tools and apt was yours, can you have a look at this?
Comment 23 Tomáš Golembiovský 2020-06-30 16:41:53 UTC 
My guess is the '+' character in the RPM file name confuses the hash-checker in rhev-apt. I don't see a reason why we should list the linux RPMs in CDHashes.txt. Those files are never going to be installed by rhev-apt so we don't necessarily have to verify them. Easiest solution would be to remove all of them from the file.
Comment 26 Tomáš Golembiovský 2020-06-30 16:43:56 UTC 
Note that this needs to be fixed before release as it breaks the rhev-apt functionality for all Windows guests.
Comment 35 Lev Veyde 2020-07-01 14:22:49 UTC 
Looks like the issue has to do with the Windows limitation of reading only the first 64 characters of the filename, even though their own documentation suggests that they support up to 110 Unicode characters in filename for Joliet based CDFS.
As a note there is no similar issue with reading the ISO on Linux.

Recently added Linux EL8 Qemu-Guest Agent RPM has a filename which exceeds this limitation, and this what caused this issue.

Fixing this by renaming the RPM, so that it will work with the Windows limitation.

Ming, can you please verify that the fixed build works for you?

Verified as per bug 1753914 is verified, don't have other means of testing this as I have no VMWare instance available.
Unless there are steps to reproduce without virt-v2v I have no idea what to test here anyway.
