Hello, I need to generate a unique ID, so far I''ve unit tested this under 100000 iterations and it seems to work : now.to_i.to_s + ''-'' + now.usec.to_s + ''-'' + rand(1000).to_s Is there a better way ? Thanks Notes : 1) without usec, few percents of generated values are not uniques 2) the id generated is a string so the presence of

I have been storing the output of facter in a database with the assumption that uniqueid was actually unique, until I found that it is the same for a handful of my machines. It appears that uniqueid is set from the output of hostid. I checked into hostid and it gets its value from gethostid(). The following link, http://www.opengroup.org/onlinepubs/009695399/functions/gethostid.html, states,

This is useful for probing probing for cache files such as: external_command ?ignore_error:(Some true) ~prog "ls .cache/something.*" will return command output (matched files) on its success or empty list whenits exit code is other than 0 (there are no such files). --- mllib/common_utils.ml | 15 ++++++++++----- mllib/common_utils.mli | 2 +- 2 files changed, 11 insertions(+), 6

This is like the Perl chomp function, it removes a single \n from the end of a string if present, else leaves the string alone. I believe I found the only (two) places where such a function is used, but there may be a few more lurking. --- common/mlstdutils/std_utils.ml | 7 +++++++ common/mlstdutils/std_utils.mli | 2 ++ common/mlstdutils/std_utils_tests.ml | 10 ++++++++++

Just wanted to share some success I had moving some Xen guests from one server to another. Problem Recap We had Xen host on a single core 32-bit CentOS 5.4 installation on an AMD Athlon 2.1 GhZ system that was giving hard drive errors and needed to move the LVM-backed Xen images to another server. The replacement server was a quad-core AMD Phenom system running 64-bit CentOS 5.4. Our original

This patcheset fixes errors in virt-sysprep and virt-sparsify. Here we have a common functionality: is_btrfs_subvolume. Doesn't it make sense to turn it into guestfs API? Also I found an issue. In 'virt-sysprep fs-uuids', the uuids for ALL filesystems are regenerated as many times as many roots are in guest. Is it done intentionally? Maxim Perevedentsev (3): mllib: add checking

The change is not correct in case the OVF is used in -o vdsm mode, for example. Let's revert it, and then implement it properly.

Newer versions of e2fsprogs refuse modifying journal devices, causing the test #1 of get_e2uuid to fail with: libguestfs: error: set_e2uuid: Cannot modify a journal device. Since the test case just needs to verify get_e2uuid runs without failing, run it without expecting a certain UUID set earlier.

Hi, I install a guest Fedora inside the host Fedora. When I use the service xend status to check the status of xend. It shows xend is running. However when I use xm create xen1 to start the guest domain xen1, it failed. The corresponding file xen1 is in /etc/xen/xen1. The error msg is as follows: [root@phillis xen]# xm create xen1 Using config file "./xen1". Going to boot Fedora

I'm trying to build xapian-core-1.2.2 on Linux. After manually installing uuid.h and libuuid.a from e2fsprogs-1.41.12, I receive the following configure error: checking for uuid.h... yes checking for uuid_create... no configure: error: uuid.h found, but uuid_create() not found.
