[Libvir] PATCH: Fix block device numbers for virDomainBlockStats
by Daniel P. Berrange 29 Jan '08

29 Jan '08

As mentioned in this thread: http://www.redhat.com/archives/libvir-list/2008-January/msg00475.html The code for calculating block devices numbers has a number of flaws. This patch fixes the flaws and adds a comprehensive test program to validate it. The test program also validates invalid cases. NB, this code is actually now more perfect than Xen, since Xen doesn't handle SCSI disks > sdp, even though you can go all the way to sdhv. The rules are: * hdNM: N=a-t, M=1-63, major={IDE0_MAJOR -> IDE9_MAJOR} * sdNM: N=a-z,aa-hw, M=1-15, major={SCSI_DISK0_MAJOR -> SCSI_DISK15_MAJOR} * xvdNM: N=a-p, M=1-15, major=XENVBD_MAJOR Which translates to the formulas xvdNM: (XENVBD_MAJOR * 256) + (disk * 16) + part; sdNM: (majors[disk/16] * 256) + ((disk%16) * 16) + part hdNM: (majors[disk/2] * 256) + ((disk % 2) * 63) + part; The SCSI/IDE formulas lookup the major number in a table since they are allocated non-contigously. The test case validates these: $ ./statstest xvda == 51712 OK xvda1 == 51713 OK xvda15 == 51727 OK xvdp == 51952 OK xvdp1 == 51953 OK xvdp15 == 51967 OK xvdq == -1 OK xvd1 == -1 OK xvda16 == -1 OK xvda0 == -1 OK hda == 768 OK hda1 == 769 OK hda63 == 831 OK hdd == 5695 OK hdd1 == 5696 OK hdd63 == 5758 OK hdt == 23359 OK hdt1 == 23360 OK hdt63 == 23422 OK hdu == -1 OK hd1 == -1 OK hda64 == -1 OK hda0 == -1 OK sda == 2048 OK sda1 == 2049 OK sda15 == 2063 OK sdp == 2288 OK sdp1 == 2289 OK sdp15 == 2303 OK sdq == 16640 OK sdq1 == 16641 OK sdq15 == 16655 OK sdz == 16784 OK sdz1 == 16785 OK sdz15 == 16799 OK sdaa == 16800 OK sdaa1 == 16801 OK sdaa15 == 16815 OK sdab == 16816 OK sdab1 == 16817 OK sdab15 == 16831 OK sdba == 17216 OK sdba1 == 17217 OK sdba15 == 17231 OK sdiv == 34800 OK sdiv1 == 34801 OK sdiv15 == 34815 OK sdix == -1 OK sd1 == -1 OK sda16 == -1 OK sda0 == -1 OK /dev == -1 OK /dev/ == -1 OK /dev/xvd == -1 OK /dev/xvda == 51712 OK /dev/xvda1 == 51713 OK /dev/xvda15 == 51727 OK The patch also fixes a couple of error codes to be INTERNAL_ERROR rather than NO_SUPPORT, because the latter is for APIs which are not supported, where as the conditions here are simply errors that shouldn't happen.

[Libvir] update after changing XML
by Maxwell Bottiger 29 Jan '08

29 Jan '08

Hi, I changed some of the XML for a qemu virtual machine. The original file was generated by virt-manager, but I wanted to use bridged networking as described in the documentation on the libvirt website. Is there something I need to for my xml changes to show up in the virtual machine? Right now my VM will not start because it's looking for it's old network configuration. -Max This e-mail and any files transmitted with it may be proprietary and are intended solely for the use of the individual or entity to whom they are addressed.

[Libvir] [PATCH] virtinst: don't expect non-root users to have block device access
by Guido Guenther 29 Jan '08

29 Jan '08

Hi, attached patch drops the assumption that a non-root user has read access to the guest OSes partition - he doesn't need to since all interaction is handled via libvirt and giving the user read access for a simple MBR block read test seems like overkill. Please apply if appropriate, patch is against current hg.

[Libvir] [PATCH] Avoid link errors with "configure --disable-shared".
by Jim Meyering 29 Jan '08

29 Jan '08

I tried to build static binaries in the usual libtool way, via "configure --disable-shared" and got some link errors due to the tests linking only with shared-lib-related files. Here's the fix: Avoid link errors with "configure --disable-shared". * tests/Makefile.am (LDADDS): Add ../src/libvirt.la, so that "configure --disable-shared" no longer provokes link errors. --- tests/Makefile.am | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/tests/Makefile.am b/tests/Makefile.am index dfd9e34..1b5f287 100644 --- a/tests/Makefile.am +++ b/tests/Makefile.am @@ -33,6 +33,7 @@ LDADDS = \ $(SASL_LIBS) \ $(WARN_CFLAGS) \ $(LIBVIRT) \ + ../src/libvirt.la \ ../gnulib/lib/libgnu.la \ $(COVERAGE_LDFLAGS) -- 1.5.4.rc5.1.g0fa73

[Libvir] 2/8 Add framework for code style- and syntax-checking rules.

Add framework for code style- and syntax-checking rules. Almost all tests are initially disabled via the list in Makefile.cfg. * Makefile.am (EXTRA_DIST): Add .x-sc_avoid_if_before_free. Omit names of files that automake includes automatically. * .x-sc_avoid_if_before_free: New file. * build-aux/vc-list-files: Likewise. * build-aux/find-unnecessary-if-before-free: Likewise. * GNUmakefile, Makefile.cfg, Makefile.maint: New files.

[Libvir] [PATCH] Plug test-related leaks

Once I had a static "virsh" binary, I ran this: cd src && valgrind --leak-check=full ./virsh --connect \ test://$PWD/../docs/testnode.xml list which exposed some leaks.
