Eric, thanks for reply but I'm having some issues now...
I've pulled libvirt sources from upstream and I'm unable to compile it
since it keeps saying following:
CCLD libvirt_parthelper
./.libs/libvirt_util.a(libvirt_util_la-util.o): In function
`virFileOperationNoFork':
/home/mig/Work/virt-related/libvirt/src/util/util.c:1363: undefined
reference to `rpl_open'
Huh. rpl_open is a gnulib replacement for open(); I'm not sure why
gnulib thinks open() needs replacing on Linux (unless it is trying to
provide O_CLOEXEC support for older kernels). Was this an incremental
build, where you had already built before updating to the latest
libvirt.git, and just typed 'make'?
Can you try 'rm gnulib/lib/fcntl.h', then 'make', to see if it clears up
the issue? If it doesn't, then maybe you'll have to resort to a
full-blown clean checkout.
I have already solved this one by `make maintainer-clean` which cloned
the gnulib again.
Unfortunately I was unable to find definition of 'rpl_open' function
using git grep so I don't really know what to do there. Some bug or do I
miss something?
It's defined by gnulib, which is copied into place from the gnulib.git
submodule during ./autogen.sh (and not under libvirt.git's control).
Even then, it only exists in the replacement<fcntl.h> header provided
by gnulib when gnulib thinks that open() isn't up to snuff with POSIX
requirements.
OK
Basically I don't know what you mean by this. Also, when I was defining
XMLs I saw that the console node copies the first serial node however
how to define it if first serial node is just none?
I mean the XML is like:
<serial type='dev'>
<source path='/dev/ttyS0'/>
<target port='0'/>
</serial>
<serial type='dev'>
<source path='/dev/ttyS1'/>
<target port='1'/>
</serial>
<console type='dev'>
<source path='/dev/ttyS0'/>
<target port='0'/>
</console>
But what should the XML part be for case of first serial device to be
none ?
I think the key is the<target port='1'/>. You don't need any
placeholder in the XML for a missing port 0, but you do need it in the
xm format where port is implied by position. That is:
<devices>
<serial type='dev'>
<source path='/dev/ttyS1'/>
<target port='1'/>
</serial>
</devices>
should be sufficient XML to mark that you want to use multi-serial xen
support, and that you are explicitly leaving virtual port 0 unoccupied
and plugging in your one serial device into virtual port 1; mapping to:
serial = [ "none", "/dev/ttyS1" ]
in the xm file. The sexpr rationale should be the same.
Ah, ok, sounds good. Thanks!
