[libvirt] [PATCH] qemu: Don't use legacy USB for aarch64 mach-virt guests
by Andrea Bolognani 20 Jun '16

20 Jun '16

The '-usb' option doesn't have any effect for aarch64 mach-virt guests, so the fact that it's currently enabled by default is not really causing any issue. However, that might change in the future (although unlikely), and having it as part of the QEMU command line can cause confusion to someone looking through the process list. Avoid it completely, like it's already happening for q35. --- This requires https://www.redhat.com/archives/libvir-list/2016-June/msg01157.html to apply cleanly, but it's not really related. Applying it on top of master instead should just be a matter of fixing a few trivial merge conflicts in the test suite. CC:ing Drew for extra assurance that doing this is indeed completely safe :) src/qemu/qemu_command.c | 1 + tests/qemuxml2argvdata/qemuxml2argv-aarch64-aavmf-virtio-mmio.args | 1 -

(CCing libvirt list) As we shouldn't make machine-type changes introduce new host requirements, it looks like we need to either add a new set of CPU models (unreasonable), or expect management software to explicitly enable LMCE after ensuring the host supports it. Or we could wait for a reasonable time after the feature is available in the kernel, and declare that QEMU as a whole requires a newer kernel. But how much time would be reasonable for that? Long term, I believe we should think of a better solution. I don't think it is reasonable to require new libvirt code to be written for every single low-level feature that requires a newer kernel or newer host hardware. Maybe new introspection interfaces that would allow us to drop the "no new requirements on machine-type changes" rule? -- Eduardo

[libvirt] Question: forbid dnsmasq to install IPv6 default route

Hello guys! I got into problem with installing IPv6 default gateway on centos7 guest while running dhcpv6. === Scheme === Guest has two network interfaces. *eth0* is connected to Host-Only network over virbr0. This network has dhcpv6 set up. [root@s143 ~]# virsh net-dumpxml Host-Only <network connections='1'> <name>Host-Only</name> <uuid>11aa4e6a-9014-4dae-86b9-b13159896efe</uuid> <bridge name='virbr0' stp='off' delay='0'/> <mac address='52:54:00:1e:17:49'/> <ip family='ipv4' address='10.37.130.2' prefix='24'> <dhcp> <range start='10.37.130.1' end='10.37.130.254'/> </dhcp> </ip> <ip family='ipv6' address='fdb2:2c26:f4e4::1' prefix='64'> <dhcp> <range start='fdb2:2c26:f4e4::' end='fdb2:2c26:f4e4::ffff'/> </dhcp> </ip> </network> *eth1* is connected to Bridged network over br0 bridge on host enp4s0 interface. [root@s143 ~]# virsh net-dumpxml Bridged <network connections='1'> <name>Bridged</name> <uuid>1ffa16f9-6a52-4710-9b58-52b8463cdece</uuid> <forward mode='bridge'/> <bridge name='br0'/> </network> [root@s143 ~]# virsh iface-dumpxml br0 <interface type='bridge' name='br0'> <protocol family='ipv4'> <ip address='10.94.1.161' prefix='16'/> </protocol> <protocol family='ipv6'> <ip address='2001:aaad::a5e:a28E' prefix='64'/> <ip address='fe80::be5f:f4ff:fe44:2cbb' prefix='64'/> </protocol> <bridge> <interface type='ethernet' name='vme42460d71'> <link state='unknown'/> <mac address='fe:1c:42:46:0d:71'/> </interface> <interface type='ethernet' name='enp4s0'> <link speed='1000' state='up'/> <mac address='bc:5f:f4:44:2c:bb'/> </interface> </bridge> </interface> === Problem === Now I want to set ipv6 address 2001:aaad::a5e:a28F to guest eth1 (bridged to host) and install a default route ip -6 route add default via 2001:aaad::a5e:a290 dev eth1 // metric 1024 So I want all the IPv6 traffic w/o route to go into eth1, then through host bridge to gateway (same for host and guest). The problem is that I see following in my guest: // the metric changes somehow, but this does not matter. default via fe80::5054:ff:fe1e:1749 dev eth0 proto static metric 100 pref medium default via 2001:aaad::a5e:a290 dev eth1 metric 1024 pref medium And the first (via link-local) route is preferred on routing. [root@s143 ~]# ip -6 address show dev virbr0 6: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 inet6 fdb2:2c26:f4e4::1/64 scope global valid_lft forever preferred_lft forever inet6 fe80::5054:ff:fe1e:1749/64 scope link valid_lft forever preferred_lft forever The problem is: guest:/ # radvdump # # radvd configuration generated by radvdump 2.11 # based on Router Advertisement from fe80::5054:ff:fe1e:1749 # received by interface eth0 # interface eth0 { AdvSendAdvert on; # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump AdvManagedFlag on; AdvOtherConfigFlag on; AdvReachableTime 0; AdvRetransTimer 0; AdvCurHopLimit 64; AdvDefaultLifetime 1800; <---------------- AdvHomeAgentFlag off; AdvDefaultPreference medium; AdvLinkMTU 1500; AdvSourceLLAddress on; prefix fdb2:2c26:f4e4::/64 { AdvValidLifetime 3600; AdvPreferredLifetime 3600; AdvOnLink on; AdvAutonomous off; AdvRouterAddr off; }; # End of prefix definition RDNSS fe80::5054:ff:fe1e:1749 { AdvRDNSSLifetime 3600; }; # End of RDNSS definition }; # End of interface definition So, dnsmasq includes its link-local address into RA and announces itself as default gateway valid for 30min. Guest sees this RA and installs a route in accordance. As a result, the default gateway requested by user is overridden and thus not used. We cannot just disable RA since we still need IPv6 address on guest eth0 (dhcp6 part of functionality). === Possible solutions === I see two possible solutions. 1) Tinker with routes. As I said, the metric of installed RA routes may change and it's difficult to override them for sure (maybe with metric 0 or 1?) Moreover, this may confuse user and requires specific knowledge (IPv6, RA, etc.). 2) Forbid guest to learn default route from RA sysctl -w net.ipv6.conf.eth0.accept_ra_defrtr=0 - This should be made for all virbr-based networks. - This may confuse user as well. 3) Forbid dnsmasq to announce virbr0 link-local address as default gateway. This can be made with adding 'ra-param=*,0,0' to /var/lib/libvirt/dnsmasq/Host-Only.conf // interface=* (any), interval=0 (default), router_lifetime=0 (I am NOT you gateway, Luke). // tested on dnsmasq-2.75-3.fc22 but should work from 2.67 now the RA looks as following: linux-bnqo:/ # radvdump # # radvd configuration generated by radvdump 2.11 # based on Router Advertisement from fe80::5054:ff:fe1e:1749 # received by interface eth0 # interface eth0 { AdvSendAdvert on; # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump AdvManagedFlag on; AdvOtherConfigFlag on; AdvReachableTime 0; AdvRetransTimer 0; AdvCurHopLimit 64; AdvDefaultLifetime 0; AdvHomeAgentFlag off; AdvDefaultPreference medium; AdvLinkMTU 1500; AdvSourceLLAddress on; prefix fdb2:2c26:f4e4::/64 { AdvValidLifetime 3600; AdvPreferredLifetime 3600; AdvOnLink on; AdvAutonomous off; AdvRouterAddr off; }; # End of prefix definition RDNSS fe80::5054:ff:fe1e:1749 { AdvRDNSSLifetime 3600; }; # End of RDNSS definition }; # End of interface definition === Conclusion ==== Please correct me if my setup itself is wrong and causes problems. Maybe there are another solutions possible, w/o modifying libvirt/guest? Would you accept patches related to 3rd solution? Looking forward to your replies. Thanks in advance! -- Your sincerely, Maxim Perevedentsev

[libvirt] [PATCH v2] libxl: add USB to hostdev domcapabilities
by Joao Martins 17 Jun '16

17 Jun '16

From: Jim Fehlig <jfehlig(a)suse.com> Commit 2a58ed0b added support for creating guests with USB hostdevs. Commit fc21d10 later added support for hotplut of USB hostdevs. Advertise support for USB hostdevs in the domcapabilities. In addition add the appropriate caps for USB support on domaincapstest when libvirt is built on a Xen with LIBXL_HAVE_PVUSB. Otherwise domaincapstest would fail i.e. testing the wrong domain capabilities.
