[PATCH 0/3] Add discard support.

by Richard W.M. Jones

These patches contain the beginnings of discard (a.k.a. trim or unmap) support. This will allow us to change virt-sparsify to work on disk images in-place (instead of using slow & inefficient copying). The approach used is to add an optional 'discard' parameter to add-drive. It has 3 possible settings: - 'disable' : the default, no discard is done - 'besteffort' : try to enable it, but don't fail if it's not supported - 'enable' : enable it, and fail if it is not supported I'm not sure if we should wait for post-1.26 before adding discard support. It depends if the interface above is suitable or if we'll have to change it later. However I discussed how to support this at DevConf and this approach was generally agreed. Rich.

virt-builder disk space

by Joshua Daniel Franklin

Hi, I've got a feature request, it would be nice to have some friendly info in the case you don't have enough disk space on the default locations for virt-builder and supermin to run. I was using virt-builder on the official Fedora AMI on EC2 which includes an awesome 2G root block device and, since RAM is at a premium in the smaller instance types, tmpfs is not used. http://fedoraproject.org/en/get-fedora-options#clouds However, EC2 also includes direct-attached "Instance Storage" scratch space such as 160G magnetic on m1.small or 32G ssd on m3.large (details at http://aws.amazon.com/ec2/pricing/ ) which cloud-init automatically mounts at /mnt. All you get output wise is : virt-builder: libguestfs error: /usr/bin/supermin-helper exited with error status 1. Even with LIBGUESTFS_DEBUG and LIBGUESTFS_TRACE supermin isn't super helpful but you can see lines such as: libguestfs: trace: get_cachedir = "/var/tmp" /usr/bin/supermin-helper: ext2fs_read_inode: Illegal inode number This works fine: export TMPDIR=/mnt virt-builder --cache /mnt fedora-20 More output attached. I love virt-builder btw.

FYI: Fwd: [Bug 1157665] Re: update-guestfs-appliance & ligbuestfs-test-tool should be included in libguestfs0

by Richard W.M. Jones

Hi Hilko, I don't know if you pay attention to or even care about Ubuntu bugs. I subscribe to ones that involve libguestfs, and one here [see below] involves libguestfs packaging in Debian/Ubuntu. Unfortunately Ubuntu LTS has settled on a really old version of libguestfs too ...

I'm not sure this is a right choice. I think they should be under libguestfs0 as they are in Debian. All the applications that use the library should work out of the box when you install them using "apt- get install". For example guestmount has libguestfs0 as a dependency but not liguestfs-tools.

Hivex3: Saving values - always string

by Martin Klíma

Hallo, I working on GUI interface for users to manipulate Windows Registry. For that I choose to use really excellent library hivex3. Just now I'm performing same test to see, if everything is saved correctly. Most of things work really well, but there is problem with saving some values and his types. Description of problem: For saving values is used function : node_set_values or node_set_value This function take 3 arguments, node name, value type and value. It seems that this function accept for value only strings (any other type throw error). The problem lay when I want save values differed then string. For example: value1 = { "key": "TEST_DWORD2(150)", "t": 4, "value": "150" } Result is saving value "150" not like DWORD but like STRING -> 0x313530, which is not valid DWORD value for Win Regedit. This same is with saving binary values, binary or hex is handle like string. So is there any way how to force library to take this type correctly? I'm using: hivex3 - 1.3.7 python - 2.7.5 Thanks for any advice
