[PATCH v2] rpm: Choose providers better (RHBZ#1266918).

by Richard W.M. Jones

This is v2 of the 4/4 patch from the original series. Changes: - memoize the function this time - check packages are installed using rpm_package_of_string However I didn't combine the two case together, because the code is a bit simpler with them separate. Rich.

[PATCH 0/4] v2v: Use libvirt-supplied <vmware:datacenterpath> if available.

by Richard W.M. Jones

See earlier thread on libvir-list: https://www.redhat.com/archives/libvir-list/2015-September/thread.html#00201 Libvirt >= 1.2.20 supplies the correct dcPath parameter. If it is available in the libvirt XML, use it, otherwise fall back to the old method of trying to guess it from the vpx:// path. Patches 1, 2 and 4 are just refactoring around this change. Rich.

[PATCH] v2v: Add xpath_int64 functions, and use them to read memory values.

by Richard W.M. Jones

On 32 bit platforms, reading the memory values can cause some numbers to be read as negative numbers.

[PATCH 0/6] v2v: assorted improvements to tests for windows

by Roman Kagan

This series makes several enhancements to tests for v2v conversion of Windows guests. Specifically, it - adds a number of files which imitate the stuff that is supposed to be present on the host when the actual conversion is performed, but may not be there when the tests are run. This includes certain tools and virtio drivers - fixes the test for windows conversion to actually check that the guest filesystem contains the expected files and directories upon conversion - adds a test for the case when virtio windows drivers are provied on an iso image - fixes a bogus failure case in a utility function which triggered on the newly added fake virio windows driver directory. Roman Kagan (6): tests: use fake rhsrvany.exe tests: add fake rhev-apt.exe v2v:test:win: actually check the eventual layout tests: use fake virtio-win drivers v2v:utils: ignore files w/o extension add test for v2v with virtio-win drivers on iso Makefile.am | 1 + configure.ac | 1 + p2v/test-virt-p2v-pxe.sh | 10 ++--- p2v/test-virt-p2v.sh | 9 ++--- tests/fake-virt-tools/rhev-apt.exe | 1 + tests/fake-virt-tools/rhsrvany.exe | 1 + tests/fake-virtio-win/.gitignore | 1 + tests/fake-virtio-win/Makefile.am | 34 ++++++++++++++++ tests/fake-virtio-win/drivers/i386/Win7/netkvm.cat | 1 + tests/fake-virtio-win/drivers/i386/Win7/netkvm.inf | 1 + tests/fake-virtio-win/drivers/i386/Win7/netkvm.sys | 1 + tests/fake-virtio-win/drivers/i386/Win7/qxl.cat | 1 + tests/fake-virtio-win/drivers/i386/Win7/qxl.inf | 1 + tests/fake-virtio-win/drivers/i386/Win7/qxl.sys | 1 + .../fake-virtio-win/drivers/i386/Win7/vioscsi.cat | 1 + .../fake-virtio-win/drivers/i386/Win7/vioscsi.inf | 1 + .../fake-virtio-win/drivers/i386/Win7/vioscsi.sys | 1 + .../fake-virtio-win/drivers/i386/Win7/viostor.cat | 1 + .../fake-virtio-win/drivers/i386/Win7/viostor.inf | 1 + .../fake-virtio-win/drivers/i386/Win7/viostor.sys | 1 + tests/regressions/rhbz1232192.sh | 7 +--- v2v/Makefile.am | 1 + v2v/test-v2v-cdrom.sh | 7 +--- v2v/test-v2v-i-disk.sh | 7 +--- v2v/test-v2v-i-ova-formats.sh | 7 +--- v2v/test-v2v-i-ova-gz.sh | 7 +--- v2v/test-v2v-i-ova-two-disks.sh | 8 ++-- v2v/test-v2v-i-ova.sh | 8 ++-- v2v/test-v2v-networks-and-bridges.sh | 6 +-- v2v/test-v2v-no-copy.sh | 6 +-- v2v/test-v2v-o-glance.sh | 6 +-- v2v/test-v2v-o-libvirt.sh | 6 +-- v2v/test-v2v-o-null.sh | 6 +-- v2v/test-v2v-o-qemu.sh | 6 +-- v2v/test-v2v-o-rhev.sh | 6 +-- v2v/test-v2v-o-vdsm-options.sh | 6 +-- v2v/test-v2v-oa-option.sh | 6 +-- v2v/test-v2v-of-option.sh | 6 +-- v2v/test-v2v-on-option.sh | 6 +-- v2v/test-v2v-sound.sh | 6 +-- ...ws-conversion.sh => test-v2v-virtio-win-iso.sh} | 45 ++++++++++++++-------- v2v/test-v2v-windows-conversion.sh | 35 +++++++++++------ v2v/utils.ml | 5 +-- 43 files changed, 140 insertions(+), 139 deletions(-) create mode 100644 tests/fake-virt-tools/rhev-apt.exe create mode 100644 tests/fake-virt-tools/rhsrvany.exe create mode 100644 tests/fake-virtio-win/.gitignore create mode 100644 tests/fake-virtio-win/Makefile.am create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/netkvm.cat create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/netkvm.inf create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/netkvm.sys create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/qxl.cat create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/qxl.inf create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/qxl.sys create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/vioscsi.cat create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/vioscsi.inf create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/vioscsi.sys create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/viostor.cat create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/viostor.inf create mode 100644 tests/fake-virtio-win/drivers/i386/Win7/viostor.sys copy v2v/{test-v2v-windows-conversion.sh => test-v2v-virtio-win-iso.sh} (65%) -- 2.4.3

fetching virt-p2v GUI on fedora 21

by M R, Chengappa (NFV BU)

We need one simple deployment of converting a given server with some OS converted to a Virtual Machine. i.e. -> to have a simple Linux/fedora machine and install apache or any web server for testing or any application for that matter - the purpose here is to see if this application works after the conversion to a virtual machine -> Convert P2V using the tools. -> Start virtual machine and see if works. We have our conversion server in place, but we would like to know how could we initiate virt-p2v GUI from my physical server, we have difficulties understanding this -> When you start virt-p2v, you'll see a graphical configuration dialog that walks you through connection to the conversion server, asks for the password, which local hard disks you want to convert, and other things like the name of the guest to create and the number of virtual CPUs to give it. How do we start virt-p2v on a fedora 21 Further, we see this: [root@localhost ~]# yum install virt-p2v Loaded plugins: langpacks updates/21/x86_64/metalink | 14 kB 00:00:00 updates | 4.7 kB 00:00:00 No package virt-p2v available. Error: Nothing to do [root@localhost ~]# virt-p2v --help bash: virt-p2v: command not found... Could you please help us with the steps in getting up the GUI Sorry if this is very basic and if it seems to be a stupid question, apologize upfront as we are taking a stab @ it for the first time... Awaiting for response patiently.... Thanks & Regards, Chengappa
