[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH OSSTEST v3] Allow per-host TFTP setup
I run osstest against machines which are in both the XenServer and XenClient
administrative domains, and hence which have different TFTP servers, accessible
locally via different NFS mounted paths.
Make it possible to specify various bits of TFTP path via ~/.xen-osstest/config
by introducing the idea of Tftp "scope" and allowing that to be configurable on
a per-host basis. For example I have:
TftpDefaultScope xenserver
TftpPath_xenserver /usr/groups/netboot/
TftpPxeDir_xenserver pxelinux.cfg/
TftpPath_xenclient /home/xc_tftpboot/pxe/
TftpPxeDir_xenclient /
TftpPxeTemplates_xenclient %ipaddrhex%/pxelinux.cfg
HostProp_marilith-n4_TftpScope xenclient
and I am now able to install on both cam-st16 (a xenserver world test box) and
marilith-n4 (an osstest machine hosted in the xenclient network) without
messing around with my configuration every time. I ran build-$ARCH,
build-$ARCH-pvops and test-$ARCH-$ARCH-xl in both cases.
Per-host Tftp settings are now in the $ho->{Tftp} hash instead of in $c.
$c{TftpHost} is unused -- remove the setting of its default.

v3: README improvements, use foreach to define ->{Tftp}{_}
v2: Do not allow TftpDiVersion to be a host var, this must be push gated.
Implement scope scheme
