[libvirt] [PATCH] pci: fix link maximum speed detection
by Marek Marczykowski-Górecki 18 May '17

18 May '17

Commit 8e09663 "pci: recognize/report GEN4 (PCIe 4.0) card 16GT/s Link speed" introduced another speed into enum, but mistakenly also altered field width, so one bit of link width was included there.

[libvirt] [PATCH] virDomainDefCheckABIStabilityFlags: Check for memoryBacking
by Michal Privoznik 18 May '17

18 May '17

https://bugzilla.redhat.com/show_bug.cgi?id=1450349 Problem is, memoryBacking is part of guest ABI. Therefore changing it on migration/restore from an image can lead qemu/guest to rejecting the image. At the same time, move other partial checks of virDomainMemtune into the same function: virDomainMemtuneCheckABIStability.

[libvirt] [PATCH v3 00/31] Implement sparse streams for libvirt
by Michal Privoznik 17 May '17

v3 of: https://www.redhat.com/archives/libvir-list/2017-April/msg00671.html All the patches can be found on my github: https://github.com/zippy2/libvirt/tree/sparse_streams2 diff to v2: - renamed APIs from Skip & GetHoleSize to SendHole & RecvHole - switched from 'unsigned long long len' to 'long long len' (where len is size of a hole) - introduced @flags to public APIs for future extensibility - couple of coding style fixes - couple of fixes suggested by John in review of v2 As expressed earlier, a lot of these patches should have Reviewed-by tag as John reviewed majority of them. But we don't have a clear agreement when to use the tag, so I'm not putting it in just yet. However, will do before pushing. Some patches were ACKed. However, changes described above changed them, so I'm not sure ACK still stands.

[libvirt] [PATCH] virsh: add --io when attaching disks to guests
by Gordon Messmer 17 May '17

17 May '17

virt-install and virt-manager both default to explicitly setting "io='native'" in the disk "driver" tag. virsh, however, does not and also does not provide an option to specify that setting at all. As a result, disks use a different IO mechanism (the default, "threads") when attached post-setup using virsh. Adding this option allows users to keep disk performance consistent for disks attached at install, and those attached afterward. --- tools/virsh-domain.c | 14 +++++++++++--- tools/virsh.pod | 3 ++- 2 files changed, 13 insertions(+), 4 deletions(-) diff --git a/tools/virsh-domain.c b/tools/virsh-domain.c index 0d19d0e..5c42021 100644 --- a/tools/virsh-domain.c +++ b/tools/virsh-domain.c @@ -267,6 +267,10 @@ static const vshCmdOptDef opts_attach_disk[] = { .type = VSH_OT_STRING, .help = N_("cache mode of disk device") }, + {.name = "io", + .type = VSH_OT_STRING, + .help = N_("io policy of disk device") + }, {.name = "type", .type = VSH_OT_STRING, .help = N_("target device type") @@ -504,8 +508,9 @@ cmdAttachDisk(vshControl *ctl, const vshCmd *cmd) virDomainPtr dom = NULL; const char *source = NULL, *target = NULL, *driver = NULL, *subdriver = NULL, *type = NULL, *mode = NULL, - *iothread = NULL, *cache = NULL, *serial = NULL, - *straddr = NULL, *wwn = NULL, *targetbus = NULL; + *iothread = NULL, *cache = NULL, *io = NULL, + *serial = NULL, *straddr = NULL, *wwn = NULL, + *targetbus = NULL; struct DiskAddress diskAddr; bool isFile = false, functionReturn = false; int ret; @@ -537,6 +542,7 @@ cmdAttachDisk(vshControl *ctl, const vshCmd *cmd) vshCommandOptStringReq(ctl, cmd, "mode", &mode) < 0 || vshCommandOptStringReq(ctl, cmd, "iothread", &iothread) < 0 || vshCommandOptStringReq(ctl, cmd, "cache", &cache) < 0 || + vshCommandOptStringReq(ctl, cmd, "io", &io) < 0 || vshCommandOptStringReq(ctl, cmd, "serial", &serial) < 0 || vshCommandOptStringReq(ctl, cmd, "wwn", &wwn) < 0 || vshCommandOptStringReq(ctl, cmd, "address", &straddr) < 0 || @@ -579,7 +585,7 @@ cmdAttachDisk(vshControl *ctl, const vshCmd *cmd) virBufferAddLit(&buf, ">\n"); virBufferAdjustIndent(&buf, 2); - if (driver || subdriver || iothread || cache) { + if (driver || subdriver || iothread || cache || io) { virBufferAddLit(&buf, "<driver"); if (driver) @@ -590,6 +596,8 @@ cmdAttachDisk(vshControl *ctl, const vshCmd *cmd) virBufferAsprintf(&buf, " iothread='%s'", iothread); if (cache) virBufferAsprintf(&buf, " cache='%s'", cache); + if (io) + virBufferAsprintf(&buf, " io='%s'", io); virBufferAddLit(&buf, "/>\n"); } diff --git a/tools/virsh.pod b/tools/virsh.pod index 727acf6..f46fb4a 100644 --- a/tools/virsh.pod +++ b/tools/virsh.pod @@ -2838,7 +2838,7 @@ expected. =item B<attach-disk> I<domain> I<source> I<target> [[[I<--live>] [I<--config>] | [I<--current>]] | [I<--persistent>]] [I<--targetbus bus>] [I<--driver driver>] [I<--subdriver subdriver>] [I<--iothread iothread>] -[I<--cache cache>] [I<--type type>] +[I<--cache cache>] [I<--io io>] [I<--type type>] [I<--mode mode>] [I<--sourcetype sourcetype>] [I<--serial serial>] [I<--wwn wwn>] [I<--rawio>] [I<--address address>] [I<--multifunction>] [I<--print-xml>] @@ -2865,6 +2865,7 @@ I<mode> can specify the two specific mode I<readonly> or I<shareable>.

[libvirt] [PATCH v2] qemu: Adding 'downscript' feature for QEMU network interfaces.
by Julio Faracco 17 May '17

17 May '17

This commit adds the support for 'downscript' feature: - For QEMU command line with the option: '-net downscript=/etc/qemu-ifdown,...'. - For Domains with a network interface description: '<interface type='ethernet'> ... <downscript path='/etc/qemu-ifdown'/> ... </interface>' The options 'script' and 'downscript' accept the argument 'no' to disable the script executions. The way that the code was implemented, the XML file accepts '<[down]script path='no'>' to solve this problem. This commit updates the tests and documentation too.

[libvirt] [PATCH] qemu: driver: Allow passing disk target as top image with block commit
by Peter Krempa 17 May '17

17 May '17

Since we allow active layer block commit the users are allowed to commit the top of the chain (e.g. vda) into the backing image. The API would not accept that parameter, as it tried to look up the image in the backing chain. Add the ability to use the top level image target name explicitly as the top image of the block commit operation.

Perhaps why I ended up in the > off_t rathole before. Not sure what you mean. long long is the same size as off_t for any application that enables large file support (libvirt does that) or is compiled on 64bits. Any 32bit virt mgmt application should really enable large file support, otherwise is pretty useless. > >> + * return lseek(*fd, offset, SEEK_CUR) == (off_t) -1 ? -1 : 0; >> + * } >> + * >> + * virStreamPtr st = virStreamNew(conn, 0); >> + * int fd = open("demo.iso", O_WRONLY); >> + * >> + * virConnectDownloadSparseFile(conn, st); > > ^^ This API doesn't exist... Of course neither did > virConnectDownloadFile from whence you copied the example. Maybe both > should be 'adjusted'. Maybe. One day. For now I'm happy with this example as-is. The example should show how to set up virStreamSparseRecvAll. Michal
