Hello, I am searching for the libvirt operations for relocating LXC (system or application) containers. LXC relocation mechanism is done by checkpoint / restart. I went over libvirt API documentation and found the following methods: virDomainSave that receives a domain and path to state file. The method saves domain's memory contents into a disk file. virDomainRestore that receives a domain

Hi there, There is some special reason to require a virConnectPtr param in virDomainRestore ? Regards, Camilo -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://listman.redhat.com/archives/libvirt-users/attachments/20100609/69932c54/attachment.htm>

Hi: When I make snapshot use virDomainSave,before I resume the snapshot , I use virDomainSaveImageDefineXML change the domain info, like disk path. but I can't change the <devices> , for example detach a disk or interface, Can't tell me what can I change use virDomainSaveImageDefineXML before resume snapshot.

Hi administrator, I am a cloud compute developer. I need some help from you about libvirt. I have a work to modify a image file which is saved by virDomainSave() or virDomainSaveFlags().&nbsp;So virDomainSaveImageGetXMLDesc() and virDomainSaveImageDefineXML() are APIs I choosed to do. Because I found a sentence: A save file can be inspected or modified slightly with

Hi all, I'm testing the memory hotplugging on devstack (ocata version). According to the article in https://medium.com/@juergen_thomann/memory-hotplug-with-qemu-kvm-and-libvirt-558f1c635972 , I'm trying to create a virtual machine by setting <maxMemory>. However, I've got an error message in libvirt log as below. 2017-07-20 20:33:21.175+0000: 529: error :

Hi all, I guess my question is stupid and has been asked a thousand times but i was wondering if it's possible to do the following things: - Cloning of a running virtual machine (hot copy) - Migrate a physical server to a virtual one. I googled a bit and am not able to find the answers. Thanks. Regards, Sam -------------- next part -------------- An HTML attachment was scrubbed... URL:

Greetings, I am developing a platform for test and debug use. The typical scenario I want to realize is the following: I run a .qcow2 image via QEMU-KVM, the running OS is not relevant. I want to take several snapshots of both Disk and RAM status; same file, separate files doesn't matter. I just need a way to have consistent information about them (better with XML description) and the data

Hi, I just run a ./configure --enable-R-shlib; make; make check; with a recent (11.6.2001) R-devel snapshot on Tru64 4.0F (with libcxml): make check stops in base-Ex.R at: > ###--- >>> `plot.window' <<<----- Set up World Coordinates for Graphics Window> > ## alias help(plot.window) > > ##___ Examples ___: > > ##--- An example for the use

I just tried the rsync version of R-1.1.0 on one of my alphas: It compiles without problems (gcc/g77 2.95.2, system is DU4.0E) but make check stops in base-Ex.R at > X <- cbind(1, 1:7) > str(s <- svd(X)); D <- diag(s$d) List of 3 $ d: num [1:2] 12.07 1.16 $ u: num [1:7, 1:2] -0.0976 -0.1788 -0.2601 -0.3413 -0.4225 ... $ v: num [1:2, 1:2] -0.198 -0.980 -0.980 0.198 >

I am attaching a patch to R-0.63's configure.in file which will enable R to detect and use some special math libraries on linuxppc and mklinux. The patch provides tests for these libraries and enable/disable switches for them as well. One library is the libmoto math library which must be used in conjunction with libm (it only replaces some of libm's functions). The other is a RISC

I was reading the API reference for the libvirt, when I came across the function? virDomainMigrate and virDomainMigrate2. I am unable to find the difference between the two. Can someone please tell the difference in the application of the two? -- Abhishek

Hi, I need to debug some complex Javascript that leaks in MSIE (no leaks in Firefox though). For this purpose, I am trying to utilize programs like Drip and sIEve. Both programs fail under Wine, and my guess is, they try to use Gecko as the rendering engine (and this is not what's desired: Gecko works fine with my stuff). Now, provided that MSIE can be installed under Wine, and works, can

Does libvirt support snapshotting when the virtual disk comes from a vmdk file? http://wiki.libvirt.org/page/Snapshots#Desired_functionality seems to say no, since it says "'virsh snapshot', which requires all disk images to be qcow2". OTOH, man virsh, http://libvirt.org/formatsnapshot.html, and http://libvirt.org/formatdomain.html#elementsDisks seem to indicate more

I can almost get this to run in that the splash screen appears. So, however, does this wine error log: fixme:win32:SetCriticalSectionSpinCount critsection=0x653cf7a0: spincount=1000 not supported fixme:win32:SetCriticalSectionSpinCount critsection=0x653cf810: spincount=1000 not supported fixme:reg:RegNotifyChangeKeyValue (7c,1,5,88,1): stub fixme:shell:SHCreateShellPalette stub

[Please keep me Cc:ed since I'm not subscribed to the list!] Hi list, The tl;dr; is: with Libvirt/QEMU, should it be possible to mount a filesystem share (of type='mount') after restoring from a snapshot that was taken when the filesystem share wasn't mounted? It's pretty clear that Libvirt/QEMU (currently, at least) doesn't support taking snapshots of a live guest which

I have an oVirt engine node that currently runs the system on a qcow2 based virtual disk, and an NFS export volume on RAW. I'd like to take a snapshot before a somewhat risky upgrade of oVirt and can't with the raw image attached. Looking at the documentation for the snapshot XML, I created this XML file for the snapshot <domainsnapshot> <name>20120802</name>

Hello, I want to do a snapshot which the VM has volumes. But I want to skip the volume check when I do the snapshot. (Which means I want to do a snapshot without detaching the volume) So I try to write a snapshot XML refer by http://libvirt.org/formatsnapshot.html as following: vda is my VM basic disk (qcow2) vdb is a volume (raw) ================ t1.xml =============== <domainsnapshot>

Hi, ALL, I just look for the class and method to use blockcopy in libvirt-java on this page: http://libvirt.org/sources/java/javadoc/ However, I can not find out. Libvirt-java Support blockcopy ? Thanks. Best Regards, Star Guo
