by Wido den Hollander
Hello,
This series of patches adds functionality to libvirt-java for:
* block device resizing
* snapshot handling
* domain migration
All these patches originate from the Apache CloudStack project
and were written during development of new featurs for CloudStack.
Thank you,

[libvirt] [PATCHv4 0/2] S390: Adding support for SCLP Console
by Viktor Mihajlovski
The S390 architecture comes with a native console type (SCLP
console) which is now also supported by current QEMU.
This series is enabling libvirt to configure S390 domains with SCLP
consoles.
The domain XML has to be extended for the new console target types
'sclp' and 'sclplm' (line mode = dumb).
As usual the QEMU driver must do capability probing in order to find
out whether SCLP is supported and format the QEMU command line
for the new console type.
V2/V3 Changes:
Rebased to current master, resolving conflicts.
V4 Changes:
Rebased, changed 'since' to 1.0.2 in formatdomain.html.in

Re: [libvirt] Memory free in libvirt JNA
by Benjamin Wang (gendwang)
Hi,
I wrote a code to verify the memory leak problem as following.
C code in so:
void checkJNAMemLeak1(int **head, int *length)
{
long i = 0;
*head = (int *)malloc(sizeof(int) * 100000000);
for(i=0; i<100000000; i++)
{
(*head)[i] = 1;
}
*length = 100000000;
}
Java code:
public static void testJNAMemLeak1()
{
PointerByReference head = new PointerByReference();
IntByReference length = new IntByReference();
while(true)
{
libben.checkJNAMemLeak1(head, length);
System.out.println(length.getValue());
sleep(1);
}
}
When we check memory by top command, the virt and res will increase very quickly. When we check with jconsole, there is no memory in Java heap. Even I execute GC manually by jconsole. Nothing happen.
If I change java code as following:
public static void testJNAMemLeak1()
{
PointerByReference head = new PointerByReference();
IntByReference length = new IntByReference();
while(true)
{
libben.checkJNAMemLeak1(head, length);
System.out.println(length.getValue());
sleep(1);
libc.free(head.getValue());
}
}
public static void testJNAMemLeak1()
{
PointerByReference head = new PointerByReference();
IntByReference length = new IntByReference();
while(true)
{
libben.checkJNAMemLeak1(head, length);
System.out.println(length.getValue());
sleep(1);
libc.free(head.getValue());
}
}
Then everything works well. The virt and res will not increase.
I think we must provide the free functions for all the memory allocated by libvirt.
B.R.

Subject: RE: Memory free in libvirt JNA
Hi,
Overview Part of JNA API describes as following:
1. Description1:
If the native method returns char* and actually allocates memory, a return type of Pointer should be used to avoid leaking the memory. It is then up to you to take the necessary steps to free the allocated memory.
2. Description2:
Declare the method as returning a Structure of the appropriate type, then invoke Structure.toArray(int) to convert to an array of initialized structures of the appropriate size. Note that your Structure class must have a no-args constructor, and you are responsible for freeing the returned memory if applicable in whatever way is appropriate for the called function.
And the example code shows as following:
// Original C code
struct Display* get_displays(int* pcount); void free_displays(struct Display* displays);
// Equivalent JNA mapping
Display get_displays(IntByReference pcount); void free_displays(Display[] displays); ...
IntByReference pcount = new IntByReference(); Display d = lib.get_displays(pcount); Display[] displays = (Display[])d.toArray(pcount.getValue());
...
lib.free_displays(displays);
That's to say. All the memory allocated by native code must be freed explicitly in JNA part. We must add some free memory methods to support the memory-freeing.
Any comments?
B.R.
Benjamin Wang

As far as I understat free() is aliased as finalize() on that object so the java runtime will call free() automatically on garbage collection. I'm not a java expert, check some Java litterature for more details about how this is done and the cases where
free() might be better called directly.

[libvirt] [PATCH 00/12] Miscs of nodedev
by Osier Yang
Basicly, this set is created on the road to implement the
supports for NPIV migration [1]. Some of them are preparations
(such as the various new util functions), some of them are
fixes, and others are improvements.
Another set to support the persistent vHBA via scsi storage
pool will come soon.
Osier Yang (12):
Introduce new public API virNodeDeviceFindByWWN
remote: Wire up the remote protocol
nodedev: Implement virNodeDeviceFindByWWN
virsh: Use virNodeDeviceLookupByWWN
nodedev: Remove the unused enum
nodedev: Introduce two new flags for listAll API
util: Add one helper virReadFCHost to read the value of fc_host entry
nodedev: Use access instead of stat
nodedev: Refactor the helpers
nodedev: Dump max vports and vports in use for HBA's XML
nodedev: Fix the improper logic when enumerating SRIOV VF
nodedev: Abstract nodeDeviceVportCreateDelete as util function

[libvirt] [PATCH v2 0/2] add pci-bridge support
by liguang
Now, it's impossible to arrange devices into multi-pci-bus,
for example:
<sound model='ac97'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</sound>
<video>
<model type='cirrus' vram='9216' heads='1'/>
<address type='pci' domain='0x0000' bus='0x1' slot='0x02' function='0x0'/>
</video>
libvirt will complain about "bus != 0",
fortunately, qemu supports pci-to-pci bridge,
if we want to use multi-pci-bus, we can define
2 pci bridge controllers, then attach 1 to the other
as a subordinate pci-bus, so, 2 pci-buses appear.
for example:
<controller type='pci-bridge' index='0'/>
<controller type='pci-bridge' index='1'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0' bridge='0'/>
</controller>
<sound model='ac97'>
<address type='pci' domain='0x0000' bus='0x01' slot='0x02' function='0x0' bridge='1'/>
</sound>
<video>
<model type='cirrus' vram='9216' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0' bridge='0'/>

[libvirt] [PATCH] Convert libxl driver to Xen 4.2
by Jim Fehlig
Based on a patch originally authored by Daniel De Graaf
http://lists.xen.org/archives/html/xen-devel/2012-05/msg00565.html
This patch converts the Xen libxl driver to support only Xen >= 4.2.
Support for Xen 4.1 libxl is dropped since that version of libxl is
designated 'technology preview' only and is incompatible with Xen 4.2
libxl. Additionally, the default toolstack in Xen 4.1 is still xend,
for which libvirt has a stable, functional driver.
---
V2:
Remove 128 vcpu limit.
Remove split_string_into_string_list() function copied from xen
sources since libvirt now has virStringSplit().

[libvirt] [PATCH 0/3] add pci-bridge device and address type
by liguang
Now, it's unnecessary to arrange devices into multi-pci-bus,
for example:
<sound model='ac97'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</sound>
<video>
<model type='cirrus' vram='9216' heads='1'/>
<address type='pci' domain='0x0000' bus='0x1' slot='0x02' function='0x0'/>
</video>
libvirt will complain about "bus != 0",
fortunately, qemu supports pci-to-pci bridge,
if we want to use multi-pci-bus, we can define
2 pci bridge devices then attach 1 to the other
as a subordinate pci-bus, so, 2 pci-buses appear.
for example:
<pci-bridge type='root'/>
<pci-bridge type='subordinate'>
<address type='pci-bridge' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</pci-bridge>
<sound model='ac97'>
<address type='pci-bridge' domain='0x0000' bus='0x01' slot='0x02' function='0x0'/>
</sound>
<video>
<model type='cirrus' vram='9216' heads='1'/>
<address type='pci-bridge' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
</video>

[libvirt] [PATCH 0/6] Resolve FORWARD_NULL errors found by Coverity
by John Ferlan
Bug: https://bugzilla.redhat.com/show_bug.cgi?id=880388
This set of patches resolves "Error: FORWARD_NULL (CWE-476)" errors found
by Coverity.
John Ferlan (6):
xen: Avoid possible NULL dereference
vmware: Avoid NULL dereference for 'caps'
remote: Avoid calling virAuthConfigLookup() if 'credname' is NULL.
lxc: Check for non NULL usb prior to calling usbFreeDevice()
lxc: Avoid possible NULL dereference on *root prior to opendir().
cpu: Avoid NULL dereference
