What error are you seeing?
I did a quick test on my local Samba 4.0 + Hyper-V 2012 setup and see
an access denied error, which appears to be due the following ACL issue:
- Hyper-V connects using the machine account (machine$)
- Hyper-V connects using the login account (admin)
- admin creates VM container directory (vmdir)
- admin sets security descriptor on vmdir:
owner=admin
group=domain admins
acl[0]: machine$(inherit only)=0x001f01ff
acl[1]: machine$=0x0012008f
acl[n]...
- machine$ attempts to open a non-existing "vmdir\Virtual Machines"
path, which fails at realpath() with EPERM. The ACL on the parent
does not allow machine$ execute permission, so realpath() is unabled
to traverse. This step would succeed on Windows, as the "Bypass
traverse checking" user right is granted by default.
