From: "Richard W.M. Jones" <rjones at redhat.com> If the parent process uses a pipe (or any fd, but pipes are a particular problem), then the recovery process would hold open the file descriptor(s) of the pipe, meaning that it could not be fully closed in the parent. Because the recovery process doesn't use exec(2), this wasn't avoidable even using FD_CLOEXEC. Avoid this

https://bugzilla.redhat.com/show_bug.cgi?id=836710 https://bugzilla.redhat.com/show_bug.cgi?id=836913 There are at least two related bugs going on: (1) Linux sync(2) system call doesn't send a write barrier to the disk, so in effect it doesn't force the hard disk to flush its cache. libguestfs used sync(2) to force changes to disk. We didn't expect that qemu was caching anything

The following C test program was compiled using LLVM with -O3 option and MSVC with /O2. The MSVC one is about 600 times faster than the one compiled with the LLVM. We can see that the for loop in MSVC assembler is solved in the optimization pass more efficiently than that in LLVM. Is there an way to get a optimization result in LLVM like that of the MSVC?

This patch makes Perl strings translatable. The Perl strings end up in the PO files as usual. It does not touch the embedded POD. Internationalizing the Perl strings was pleasantly simple. Just add: use Locale::TextDomain 'libguestfs'; at the top of any *.pl or *.pm file. Then for each string in the file that you want to be translatable you place TWO underscores before it: -

I was attempting one way to solve: https://bugzilla.redhat.com/show_bug.cgi?id=1400332 "RFE: virt-builder should support templates with encrypted filesystems" However this approach doesn't really work because templates containing encrypted partitions cannot be compressed, and therefore the guest template would be a multi-gigabyte download. I better approach will likely be to use

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I was testing oz/imagefactory on 32 bit arm, you have to have kernel-lpae installed to run kvm. while you can have the regular kernel installed also. You end up having the system booting the regular kernel and you do not get kvm. Ideally supermin will work with the lpae kernel.

Add command line options to optionally disable the output of the installed application, and the guest icon. This makes the inspection slightly faster, producing a smaller XML to parse/process in case there is no interest in these details. --- inspector/inspector.c | 59 +++++++++++++++++++++++++++----------------- inspector/virt-inspector.pod | 14 +++++++++++ 2 files changed, 51

As described here previously: https://www.redhat.com/archives/libguestfs/2010-March/msg00129.html Here is the three part patch to reimplement virt-win-reg to support exporting and merging Windows Registry entries in the 'regedit' format. Tested by me on a local Windows VM. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-top is 'top'

Hello all, Subject: Not able to return object from backgroundrb worker I am trying to use xmpp4r and backgroundrb for my chat application. I am able to create a connectnion with XMPP4r through a worker in backgrounddrb. I have the problem in returning the object from the worker to my rails application. My code is as follows: class ChatWorker < BackgrounDRb::MetaWorker require

This change replaces all direct usage of a Sys::Guestfs object in virt-v2v with a Sys::VirtV2V::GuestfsHandle proxy object. The proxy does 3 things: * Holds handle initialisation code * Adds the ability to explicitly close the handle * Adds the ability to register a callback to be executed before close The cleanup code in Sys::VirtV2V::Config is updated to use the new callback mechanism.

We can use now ImageioClient to communicate with ovirt-imageio server on oVirt host. Using the client greatly simplifies the plugin, and enables new features like transparent proxy support. The client will use transfer_url if possible, or fall back to proxy_url. Since the client implements the buffer protocol, move to version 2 of the API for more efficient pread(). Another advantage the client

The current way to get the size of a filesystem is to query the size in bytes of the device. However, this gives the whole size of the device where a filesystem is stored, and it does not consider the actual size for which the filesystem is configured (e.g. in case it was shrunk). A simple reproducer for this is: $ guestfish -N test.img=fs:ext4:2G resize2fs-size /dev/sda1 1073741824 As result,

Hi all, After implementing the ToyVM::runApplication method, I run the ToyVM binary, A segmentation fault occurs on starting ToyThread.

1. Re: LLVM optmization (Bill Wendling) Hi, The IR is not wrong. I said that the assembler generated by MSVC is quicker. We can see that the for loop, in the TESTE function, is done without jump's in the MSVC and with jumps in LLVM. I think thats the point. If we don't use threads, the result is the same. My test were done with one billion interactions in the for loop. The MSVC
