Can you manually mount /dev/sdb3 ? Maybe somethings wrong with that drive?
What's the XML for that VM? sudo virsh dumpxml WIN10

For downgrade to version 4.2 use next files:

Hmm the only libvirt changes in src/storage/ between 4.1 and 4.3 are things involving the split out storage driver... I wonder if that's triggering the issue somehow? Unfortunately I don't know enough about those changes to say offhand

This problem between versions 4.2 and 4.3
Comment 20 Cole Robinson 2018-07-12 20:24:37 UTC 
Now that I look at the error message closer, it's probably due to this change:

commit fd9d1e686db64fa9481b9eab4dabafa46713e2cf

    util: Introduce virDevMapperGetTargets

Something is going wrong calling that function. Maybe Michal has ideas
Comment 21 Michal Privoznik 2018-07-13 07:24:18 UTC 
Guys, this really looks like problem caused by the commit Cole's referring to. However, the code is written so that ENOENT is ignored. Therefore I don't understand how come you can get "No such file or directory" in the commit message.

https://libvirt.org/git/?p=libvirt.git;a=blob;f=src/util/virdevmapper.c;hb=HEAD#l94

Also, I'm unable to reproduce. Can you try to attach a debugger and get exact location where virDevMapperGetTargetsImpl() fails? And what is your kernel version?
Comment 22 Sergey 2018-07-13 12:25:25 UTC 
Thanks to Michal for help. For solve problem just need activate in kernel option CONFIG_BLK_DEV_DM.
Problem is solved.
Comment 23 Michal Privoznik 2018-07-13 13:49:43 UTC 
Turns out, the problem is libvirt expected DM support to be compiled into kernel. If that's not the case this problem occurs. Patches posted upstream:

    https://bugzilla.redhat.com/show_bug.cgi?id=1591732
    
    On kernels without device mapper support there won't be
    /dev/mapper/control. Therefore it doesn't make much sense to
    put it into devices CGroup.

    virDevMapperGetTargetsImpl: Be tolerant to kernels without DM support
    
    https://bugzilla.redhat.com/show_bug.cgi?id=1591732
    
    If kernel is compiled without CONFIG_BLK_DEV_DM enabled, there is
    no /dev/mapper/control device and since dm_task_create() actually
    does some ioctl() over it creating a task may fail.
    To cope with this handle ENOENT and ENODEV gracefully.

So if you're running an older libvirt then yeah, applying those patches might be a problem for you (I'd let your distro maintainers do their job and backport the patches and ship fixed package for you). Meanwhile, you can clone libvirt repo (or if you already have one just pull so that you have the latest HEAD), build it and run libvirtd from there.
