[libvirt] [glib PATCH 0/8] Add machinery forsetting firmware attribute to <os/>
by Fabiano Fidêncio 20 May '19

20 May '19

This series consists in two different things that, together, are needed to set <os firmware="efi|bios"/> as part of libvirt domain's XML. The first patch simply changes the XML adding the bit mentioned above. All the other patches, on the other hand, add enough (and nothing more than that) infra for consumers to check which are the supported firmwares (the ones listed by virConnectGetDomainCapabilities()).

[libvirt] [PATCH 0/7] x86: Multi-key Total Memory Encryption (Intel)
by Larkins Carvalho 18 May '19

18 May '19

This patch series provides support for launching an encrypted guest using Intel's Multi-key Total Memory Encryption (MKTME) feature. The purpose of this review is to get initial feedback and to get on par with libvirt development process. Considering we have not added tests, this is a preliminary patch and based on the community feedback, we expect more updates to follow. Total Memory Encryption (TME) provides the capability to encrypt the entirety of the physical memory of a system. MKTME builds on TME and adds support for multiple encryption keys. High Level flow: 1. Management tool calls virConnectGetDomainCapabilities which calls virNodeGetMKTMEInfo. This returns an XML document that includes the following: <feature> ... <mktme supported='yes'> <keys_supported> </keys_supported> </mktme> </feature> 2. If MKTME is supported management tool requests to start a guest calling virCreateXML(). The xml would include: <launchSecurity type='mktme'> <id>m0</id> <key_type>user</key_type> <key>samplekey</key> <encryption_algorithm>aes-xts-128</encryption_algorithm> </launchSecurity> 3. Libvirt makes system call with the provided information to generate a key handle using linux keyring services. Qemu uses the key handle to launch the workload. 4. Libvirt generate the QEMU cli arg to enable the MKTME feature, a typical args looks like this: # Qemu ...\ -machine pc,memory-encryption=m0 -object mktme-guest,id=m0,handle=${serial} Intel MKTME spec: https://software.intel.com/sites/default/files/managed/a5/16/Multi-Key-Tota… TODO: Add tests for launch security of type mktme.

[libvirt] [PATCH] rpm: remove dependancy from qemu to network/storage drivers
by Daniel P. Berrangé 17 May '19

17 May '19

The libvirt-daemon-driver-qemu RPM has historically had a hard dependency on the libvirt-daemon-driver-network and libvirt-daemon-driver-storage-core packages. This was because the QEMU driver would directly call into APIs that were part of these drivers.

[libvirt] [PATCH] lib: Avoid double free when passing FDs with virCommandPassFD()
by Michal Privoznik 17 May '19

17 May '19

If an FD is passed into a child using: virCommandPassFD(cmd, fd, VIR_COMMAND_PASS_FD_CLOSE_PARENT); then the parent should refrain from touching @fd thereafter. This is even documented in virCommandPassFD() comment. The reason is that either at virCommandRun()/virCommandRunAsync() or virCommandFree() time the @fd will be closed. Closing it earlier, e.g. right after virCommandPassFD() call might result in undesired results. Another thread might open a file and receive the same FD which is then unexpectedly closed by virCommandFree() or virCommandRun().

[libvirt] [PATCH 0/4] virutil: Rework how 'udevadm settle' is called

Commit 0ba9afc6b28 introduced a logic bug where we will never save the inactive XML after a blockjob as the variable which was determining whether to do so is cleared right before.

[libvirt] surprising <backingStore type='file'> setting in domain.xml
by Thomas Stein 17 May '19

17 May '19

Hello all. My currently used versions: libvirt-5.2.0 and qemu-4.0.0. Here is my problem. I'm struggeling since a few weeks with a strange behaviour by either qemu or libvirt. After a reboot of the hardware node the $domain.xml contains suddenly a backingStore setting which was not there before reboot. Something like that: <devices> <emulator>/usr/bin/qemu-system-x86_64</emulator> <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/var/lib/libvirt/shinymail/shinymail_weekly.qcow2-2019-05-15'/> <backingStore type='file'> <format type='qcow2'/> <source file='/var/lib/libvirt/images/shinymail.qcow2'/> </backingStore> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> ... This obviousely happens after a backup has been running. The Backup Script looks like this: <snip> virsh snapshot-create-as --domain shinymail weekly --diskspec vda,file=/var/lib/libvirt/shinymail/shinymail_weekly.qcow2-$(date +%Y-%m-%d) --disk-only --atomic --no-metadata cp ... virsh blockcommit shinymail vda --active --verbose --pivot <snip> So after that "dmblklist shinymail" does show the right source file but after a reboot it tries to use the weekly snapshot again which leads to filesystem errors. Someone has an idea what could cause such a behaviour? cheers t.
