- add Supplements to install package if dmi matches [bnc#731198]
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Thu Sep 1 18:51:03 CEST 2011 - ohering@suse.de
|
||||
|
||||
- disable hyper-v-kmp
|
||||
hv_storvsc handles now IDE and SCSI disks and ata_piix is
|
||||
compiled into the kernel in SLE12, so the modprobe.conf rules
|
||||
have no meaning anymore
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Tue Jul 26 21:24:25 CEST 2011 - ohering@suse.de
|
||||
|
||||
- update hv_kvp_daemon: Cleanup kvp_get_domain_name(). If
|
||||
getaddrinfo() fails, deal with it properly (this can happen if no
|
||||
IP address has been assigned). Also, don't specify a specific
|
||||
service in the call to getaddrinfo() to make this code as generic
|
||||
as possible.
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Sun Jul 24 17:22:41 CEST 2011 - ohering@suse.de
|
||||
|
||||
- update hv_kvp_daemon: The current win7 host does not like it when
|
||||
we return the complete kernel release information. Conform to
|
||||
what the host expects.
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Fri Jun 17 15:41:33 CEST 2011 - ohering@suse.de
|
||||
|
||||
- update preun, stop_on_removal requires an argument
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Fri Jun 17 11:09:30 CEST 2011 - ohering@suse.de
|
||||
|
||||
- remove get_release_number.sh, which was added by accident
|
||||
- bump version number to 2
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Fri Jun 17 10:58:42 CEST 2011 - ohering@suse.de
|
||||
|
||||
- catch errors from daemon()
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Fri Jun 17 10:33:50 CEST 2011 - ohering@suse.de
|
||||
|
||||
- update postun to run restart_on_update
|
||||
- use rpmmacro for daemon name
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Fri Jun 17 08:10:12 CEST 2011 - ohering@suse.de
|
||||
|
||||
- update postin to work in / again when running insserv macro
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Thu Jun 16 15:33:49 CEST 2011 - ohering@suse.de
|
||||
|
||||
- Update version number to 1 so kernel.rpm can obsolete
|
||||
the old kmp packages
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Thu Jun 16 11:12:06 CEST 2011 - ohering@suse.de
|
||||
|
||||
- enable hv_kvp_daemon if run in a hv guest [fate#312213]
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Thu Apr 21 17:18:20 CEST 2011 - ohering@suse.de
|
||||
|
||||
- add hv_kvp_daemon to provide system infos to hypervisor [bnc#685189]
|
||||
this enables the hyper-v main package
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Sat Apr 16 15:13:36 CEST 2011 - ohering@suse.de
|
||||
|
||||
- Require at least kernel-default 2.6.32.27 for an empty KMP.
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Fri Apr 15 16:50:25 CEST 2011 - ohering@suse.de
|
||||
|
||||
- actually keep the KMP packages with just the modprobe.conf file
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Thu Mar 31 11:24:03 CEST 2011 - ohering@suse.de
|
||||
|
||||
- make building of kernel modules optional [bnc#676890]
|
||||
the hv*.ko drivers exist in two places, kernel-default and this
|
||||
KMP package. Both can get out of sync, then mkinitrd will use
|
||||
(the possible outdated) drivers from this KMP package.
|
||||
disable building drivers per default, keep only the
|
||||
hyperv_pvdrivers.conf
|
||||
- mark hyperv_pvdrivers.conf as config to preserve local
|
||||
modifications done by the sysadmin
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Thu Feb 24 12:09:25 CET 2011 - meissner@suse.de
|
||||
|
||||
- also add hv_timesource to Modules.supported [bnc#650748]
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Tue Jan 4 10:28:21 CET 2011 - meissner@suse.de
|
||||
|
||||
- add hv_utils to Modules.supported [bnc#650748]
|

||||
-------------------------------------------------------------------
|
||||
Wed Apr 28 11:40:33 CEST 2010 - kukuk@suse.de
|
||||
|
||||
- Next update of hyperv_pvdrivers.conf [bnc#600212]
|
||||
|
||||
-------------------------------------------------------------------
|
||||
Tue Apr 27 13:20:55 CEST 2010 - kukuk@suse.de
|
||||

-------------------------------------------------------------------
|
||||
Tue Apr 27 07:10:05 CEST 2010 - ksrinivasan@novell.com
|
||||

|
||||
|
||||
-------------------------------------------------------------------
|
||||
Mon Apr 26 18:15:40 CEST 2010 - kukuk@suse.de
|
||||
|
||||
- Add hyperv_pvdrivers.conf modprobe config file
|

|
||||
-------------------------------------------------------------------
|
||||
Fri Mar 5 13:40:56 CET 2010 - mmarek@suse.cz
