I do make a mistake because I just print os.getuid() show the user root; =
but os.geteuid() show the current user is still vdsm;
=20
Anyway , I still don=E2=80=99t know how to debug vdsm, I cann=E2=80=99t =
log in to centos with user VDSM, because I don=E2=80=99t know the passwd =
of user vdsm and if I changed the password, the service vdsmd will =
cann=E2=80=99t start.
=20
the vdsm account is intentionally disabled for interactive login
=20
You told me =E2=80=9Cshould follow the devel setup wiki=E2=80=9D , =
what=E2=80=99s the true link of vdsm devel setup wiki ? I can=E2=80=99t =
get useful information in <http://ovirt.org/> ovirt.org or google.
=20
<http://www.ovirt.org/develop/developer-guide/vdsm/developers/> =
http://www.ovirt.org/develop/developer-guide/vdsm/developers/ has tips =
how to build from source and what packages are needed
Anything specific you=E2=80=99re troubleshooting?
=20
I do build the source from this instruction , but I want to set =
breakpoint to view each step and variable value to understand the =
vdsm=E2=80=99s code using python IDE such as Pycharm ,=20
=20
You know that we can implement this debug requirement in ovirt engine =
easily, but I can=E2=80=99t implement local debug in vdsm easily, =
because vdsm didn=E2=80=99t allow root to run or debug.
=20
Is there any debug instruction ?
=20
I don=E2=80=99t think it=E2=80=99s possible to debug it from PyCharm, or =
any IDE for that matter, easily.=20
It=E2=80=99s a multithreaded application, you can=E2=80=99t really set a =
breakpoint without affecting other functionality since some of the =
threads need to keep running
Best advice is to add a debugging/logging code in places you need, =
printing variables you=E2=80=99re interested in.
=20
I know it=E2=80=99s a multithreaded application , and debug =
vdsm is a very difficult job, but without debug, I don=E2=80=99t know =
which code I should replace or logging, Is there any remote debug =
solution like ovirt engine? I found that=20
I can do remote debug in simple python application , but I =
didn=E2=80=99t success yet remote debugging vdsm.=20
=20
Now one of our case I want to consider using ovirt as our =
solution , we may do little change over ovirt. but as described above, =
without debug , we can hardly understand vdsm clearly and cannot do =
correctly code change.
Is there some good advice ?

Investitate:
According to the traceback above, the code in libvirt.py as below, and =
os.geteuid() get =E2=80=980=E2=80=99 which shows the current user is =
root;
=20
vdsm is not supposed to be run under root user. For debugging you should =
follow the devel setup wiki and not change a regular host.=20
Depends what you modified, it's impossible to say from what you =
described....but a general advice is you simply don't do that:)
=20
def openAuth(uri, auth, flags=3D0):
#print os.geteuid()
ret =3D libvirtmod.virConnectOpenAuth(uri, auth, flags)

According that, root should not get an Permission denied error ? But =
why?
=20
And I setenforce=3D0 , and still show Perssion denied error.
=20
What=E2=80=99s the reason? And how to solve it?
