[libvirt] RFC: extending domcapabilities XML
by Cole Robinson 27 Apr '16

27 Apr '16

Hi all, There's a couple qemu bits I want to expose in domcapabilities XML, but there isn't an existing pattern to follow so I'd like to get some feedback first. Hopefully it can serve as a template for future domcapabilities extensions 1) USB controller models Not strictly important for my needs, but this is an incremental step. Do we do some kind of nested XML like <controller supported='yes'> <type name='usb'/> <enum name='model'> <value>nec-xhci</value> ... </enum> </type> </controller> Or come up with a unique device-level enum name to track this, like we do for hostdev subsysType: <controller supported='yes'> <enum name='usbModel'> <value>nec-xhci</value> ... </enum> </controller> 2) new usb ports= attribute This is for the patches I just sent. There's two questions here: how does XML look like for a non-enum? Maybe: <controller supported='yes'> <parameter name='ports' supported='yes'/> </controller> (or maybe <option .../>) However, ports is only supported for type=usb model=nec-xhci. Do we represent that? If so what does the XML look like? Do we go crazy nested like: <controller supported='yes'> <parameter name='type' value='usb'> <parameter name='model' value='nec-xhci'/> <parameter name='ports' supported='yes'/> </parameter> </parameter> </controller> But that's kind of intense. It gives the illusion that we can write a parser to automatically handle additions for introspecting what libvirt supports, but in practice I don't know if that's ever going to work. Instead I think it's better to invent new top level strings to represent these types of cases, rather than try to encode an infinite level of dependency in the XML hierarchy. <controller supported='yes'> <capability name='usbXHCIPorts' supported='yes'/> </controller> The question then is if the <capability> element is the proper name. Could be <feature> too but that's quite overloaded in libvirt XML. 3) spice gl whether spice gl is supported or not is a factor of libvirt version, qemu version, and spice version that qemu was compiled against, which is a lot of pieces to track. So exposing it over domcapabilities will be nice. Something like: <graphics supported='yes'/> <enum name='spiceGL'> <value>off</value> <value>on</value> </enum> </graphics> Similarly we want to know that virtio-vga has virgl support via <acceleration accel3d='yes'/> <video supported='yes'/> <enum name='virtioVGAAccel3D'> <value>yes</value> <value>no</value> </enum> </video> Comments welcome. Thanks, Cole

[libvirt] [PATCH] rpc: Don't leak fd via CreateXMLWithFiles
by Cole Robinson 27 Apr '16

27 Apr '16

From: Ben Gray <ben.r.gray(a)gmail.com> FD passing APIs like CreateXMLWithFiles or OpenGraphicsFD will leak file descriptors. The user passes in an fd, which is dup()'d in virNetClientProgramCall. The new fd is what is transfered to the server virNetClientIOWriteMessage. Once all the fds have been written though, the parent msg->fds list is immediately free'd, so the individual fds are never closed. This closes each FD as its send to the server, so all fds have been closed by the time msg->fds is free'd. https://bugzilla.redhat.com/show_bug.cgi?id=1159766 Signed-off-by: Cole Robinson <crobinso(a)redhat.com> --- Ben's patch, my comments src/rpc/virnetclient.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/rpc/virnetclient.c b/src/rpc/virnetclient.c index 781e74c..d8ed15b 100644 --- a/src/rpc/virnetclient.c +++ b/src/rpc/virnetclient.c @@ -1177,20 +1177,21 @@ virNetClientIOWriteMessage(virNetClientPtr client, if (thecall->msg->bufferOffset == thecall->msg->bufferLength) { size_t i; for (i = thecall->msg->donefds; i < thecall->msg->nfds; i++) { int rv; if ((rv = virNetSocketSendFD(client->sock, thecall->msg->fds[i])) < 0) return -1; if (rv == 0) /* Blocking */ return 0; thecall->msg->donefds++; + VIR_FORCE_CLOSE(thecall->msg->fds[i]); } thecall->msg->donefds = 0; thecall->msg->bufferOffset = thecall->msg->bufferLength = 0; VIR_FREE(thecall->msg->fds); VIR_FREE(thecall->msg->buffer); if (thecall->expectReply) thecall->mode = VIR_NET_CLIENT_MODE_WAIT_RX; else thecall->mode = VIR_NET_CLIENT_MODE_COMPLETE; } -- 2.7.3

[libvirt] [PATCH] conf: format runtime DAC seclabel, unless MIGRATABLE
by Cole Robinson 27 Apr '16

We historically format runtime seclabel selinux/apparmor values, however we skip formatting runtime DAC values.

[libvirt] [PATCHv2] conf: log error when incorrect PCI root controller is added to domain
by Laine Stump 27 Apr '16

27 Apr '16

libvirt may automatically add a pci-root or pcie-root controller to a domain, depending on the arch/machinetype, and it hopefully always makes the right decision about which to add (since in all cases these controllers are an implicit part of the virtual machine). But it's always possible that someone will create a config that explicitly supplies the wrong type of PCI controller for the selected machinetype. In the past that would lead to an error later when libvirt was trying to assign addresses to other devices, for example: XML error: PCI bus is not compatible with the device at 0000:00:02.0. Device requires a PCI Express slot, which is not provided by bus 0000:00 (that's the error message that appears if you replace the pcie-root controller in a Q35 domain with a pci-root controller). This patch adds a check at the same place that the implicit controllers are added (to ensure that the same logic is used to check which type of pci root is correct). If a pci controller with index='0' is already present, we verify that it is of the model that we would have otherwise added automatically; if not, an error is logged: The PCI controller with index='0' must be " model='pcie-root' for this machine type, " but model='pci-root' was found instead.
