[libvirt] [PATCHv2] bhyve: domainCreateXML
by Wojciech Macek
Review-fixes, changes since last time:
- persistent flag is not reset to 0 anymore
- dom->id =vm->def->id is moved after domain startup
- duplicate of start_flags |= VIR_BHYVE_PROCESS_START_AUTODESTROY removed
- flag VIR_DOMAIN_OBJ_LIST_ADD_CHECK_LIVE is used instead of zero
- virDomainObjListRemove is called for not persistent domains in case of failure
- unnecessary checkActive removed

[libvirt] [PATCH] virsh: Separate 'create'/'modify' message for secret-define
by Li Yang
The current message of secret-define always be:
Secret 09a9736f-eedb-449c-9983-80d0ab67393f created
even you just modify the secret, perhaps this may puzzle
uses. Now this patch make the modify action output message
like this:

[libvirt] what are the differences among disk cache attribute
by longguang.yue
hi,all
there are "default", "none", "writethrough", "writeback", "directsync", "unsafe" cache options
1.
could you explain what is default and none? exactly what it does and not does?
2.
what is the difference between unsafe and (default or none)?
3.
after a long time of running , it seems that vms will slow down? do you know why?
cache hit rate goes down or kernel takes time to flush cache?
thanks

[libvirt] [PATCH 0/2] specify migration URI on setting file
by Chen Fan
Hi all,
Current virsh migrate command require specfying migration URI with
command option.
1) If user specifies --migrateuri on virsh migrate command, then the
command transfers the data to specified host.
2) If --migrateuri is not specified, the command transfers the data to host
whose name is resolved by DNS or /etc/hosts.
But we would like to specify it on setting file like file libvirt.conf of libvirt
host. the motivation is:
If user would like to increase their system's resource, and user add
one more NIC for each host. (One is for management LAN, another is for data LAN).
in this case, user would like to use "data LAN" for transfer migrate data.
Then, user can specify the NIC address for data LAN by migrateuri.
Though the migrateuri is usually stable, user must specify migrateuri
every migrate time. So, setting file for migrateuri is desirable.
in addition, if there are more KVM host, to change the migrateuri will
be too troublesome for user.
Chen Fan (2):
move virConnectGetConfigFile() to virconf.h
add default migrate uri in definition file

[libvirt] [RFC PATCH] conf: Output disk backing store details in domain XML
by Jiri Denemark
The XML for quite a complicated backing chain is shown below:
<disk type='network' device='disk'>
<driver name='qemu' type='qcow2'/>
<source protocol='nbd' name='bar'>
<host transport='unix' socket='/var/run/nbdsock'/>
</source>
<backingStore type='block' index='1'>
<format type='qcow2'/>
<source dev='/dev/HostVG/QEMUGuest1'/>
<backingStore type='file' index='2'>
<format type='qcow2'/>
<source file='/tmp/image2.qcow'/>
<backingStore type='file' index='3'>
<format type='qcow2'/>
<source file='/tmp/image3.qcow'/>
<backingStore type='file' index='4'>
<format type='qcow2'/>
<source file='/tmp/image4.qcow'/>
<backingStore type='file' index='5'>
<format type='qcow2'/>
<source file='/tmp/image5.qcow'/>
<backingStore type='file' index='6'>
<format type='raw'/>
<source file='/tmp/Fedora-17-x86_64-Live-KDE.iso'/>
<backingStore/>
</backingStore>
</backingStore>
</backingStore>
</backingStore>
</backingStore>
</backingStore>
<target dev='vdb' bus='virtio'/>
</disk>
Various disk types and formats can be mixed in one chain. The
<backingStore/> empty element marks the end of the backing chain and it
is there mostly for future support of parsing the chain provided by a
user. If it's missing, we are supposed to probe for the rest of the
chain ourselves, otherwise complete chain was provided by the user. The
index attributes of backingStore elements can be used to unambiguously
identify a specific part of the image chain.
