[libvirt] [PATCH v3 0/9] x86: Secure Encrypted Virtualization (AMD)

by Brijesh Singh

The patch series is test with QEMU recent pull which includes SEV support: https://lists.gnu.org/archive/html/qemu-devel/2018-03/msg03826.html This patch series provides support for launching an encrypted guest using AMD's new Secure Encrypted Virtualization (SEV) feature. SEV is an extension to the AMD-V architecture which supports running multiple VMs under the control of a hypervisor. When enabled, SEV feature allows the memory contents of a virtual machine (VM) to be transparently encrypted with a key unique to the guest VM. At very high level the flow looks this: 1. mgmt tool calls virConnectGetDomainCapabilities. This returns an XML document that includes the following <feature> ... <sev supported='yes'> <cbitpos> </cbitpos> <reduced-phys-bits> </reduced-phys-bits> <pdh> </pdh> <cert-chain> </cert-chain> </feature> If <sev> is provided then we indicate that hypervisor is capable of launching SEV guest. 2. (optional) mgmt tool can provide the PDH and Cert-chain to guest owner in case if guest owner wish to establish a secure connection with SEV firmware to negotiate a key used for validating the measurement. 3. mgmt tool requests to start a guest calling virCreateXML(), passing VIR_DOMAIN_START_PAUSED. The xml would include <launch-security type='sev'> <cbitpos> </cbitpos> /* the value is same as what is obtained via virConnectGetDomainCapabilities() <reduced-phys-bits> </reduced-phys-bits> /* the value is same as what is obtained via virConnectGetDomainCapabilities() <dh-cert> .. </dh> /* guest owners diffie-hellman key */ (optional) <session> ..</session> /* guest owners session blob */ (optional) <policy> ..</policy> /* guest policy */ (optional) 4. Libvirt generate the QEMU cli arg to enable the SEV feature, a typical args looks like this: # $QEMU .. -machine memory-encryption=sev0 \ -object sev-guest,id=sev0,dh-cert-file=<file>.... 5. Libvirt generates lifecycle VIR_DOMAIN_EVENT_SUSPENDED_PAUSED event 6. mgmt tool gets the VIR_DOMAIN_EVENT_SUSPENDED_PAUSED and calls virDomainGetLaunchSecretInfo() to retrieve the measurement of encrypted memory. 7. (optional) mgmt tool can provide the measurement value to guest owner, which can validate the measurement and gives GO/NO-GO answer. If mgmt tool gets GO then it resumes the guest otherwise it calls destroy() to kill the guest. 8. mgmt tool resumes the guest TODO: * SEV guest require to use DMA apis for the virtio devices. In order to use the DMA apis the virtio devices must have this tag <driver iommu=on ats=on> It is a bit unclear to me where these changes need to go. Do we need to modify the libvirt to automatically add these when SEV is enabled or we ask mgmt tool to make sure that it creates XML with right tag to enable the DMA APIs for virtio devices. I am looking for some suggestions. Using these patches we have succesfully booted and tested a guest both with and without SEV enabled. SEV Firmware API spec is available at: https://support.amd.com/TechDocs/55766_SEV-KM%20API_Specification.pdf Changes since v2: * make cbitpos, policy and reduced-phys-bits as unsigned int * update virDomainGetLaunchSecurityInfo to accept virTypedParameterPtr *params instead of virTypedParameterPtr params. Changes since v1: * rename <sev> -> <launch-security> for domain * add more information about policy and other fields in domaincaps.html * split the domain_conf support in two patches * add virDomainGetLaunchInfo() to retrieve the SEV measurement * extend virsh command to show the domain's launch security information * add test cases to validate newly added <launch-security> element * fix issues reported with 'make check' and 'make syntax-check' The complete git tree is available at: https://github.com/codomania/libvirt/tree/v3 Brijesh Singh (8): qemu: provide support to query the SEV capability qemu: introduce SEV feature in hypervisor capabilities conf: introduce launch-security element in domain qemu: add support to launch SEV guest libvirt: add new public API to get launch security info remote: implement the remote protocol for launch security qemu_driver: add support to launch security info virsh: implement new command for launch security Xiaogang Chen (1): tests: extend tests to include sev specific tag parsing docs/formatdomain.html.in | 120 ++++++++++++++++++++++++++++++++++++ docs/formatdomaincaps.html.in | 40 ++++++++++++ docs/schemas/domaincaps.rng | 20 ++++++ docs/schemas/domaincommon.rng | 39 ++++++++++++ include/libvirt/libvirt-domain.h | 17 +++++ src/conf/domain_capabilities.c | 20 ++++++ src/conf/domain_capabilities.h | 14 +++++ src/conf/domain_conf.c | 110 +++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 26 ++++++++ src/driver-hypervisor.h | 7 +++ src/libvirt-domain.c | 48 +++++++++++++++ src/libvirt_public.syms | 5 ++ src/qemu/qemu_capabilities.c | 40 ++++++++++++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_capspriv.h | 4 ++ src/qemu/qemu_command.c | 35 +++++++++++ src/qemu/qemu_driver.c | 66 ++++++++++++++++++++ src/qemu/qemu_monitor.c | 17 +++++ src/qemu/qemu_monitor.h | 6 ++ src/qemu/qemu_monitor_json.c | 105 +++++++++++++++++++++++++++++++ src/qemu/qemu_monitor_json.h | 5 ++ src/qemu/qemu_process.c | 58 +++++++++++++++++ src/remote/remote_daemon_dispatch.c | 47 ++++++++++++++ src/remote/remote_driver.c | 42 ++++++++++++- src/remote/remote_protocol.x | 20 +++++- src/remote_protocol-structs | 11 ++++ tests/genericxml2xmlindata/sev.xml | 20 ++++++ tests/genericxml2xmloutdata/sev.xml | 22 +++++++ tests/genericxml2xmltest.c | 2 + tests/qemuxml2argvdata/sev.args | 24 ++++++++ tests/qemuxml2argvdata/sev.xml | 35 +++++++++++ tests/qemuxml2argvtest.c | 2 + tests/qemuxml2xmloutdata/sev.xml | 39 ++++++++++++ tests/qemuxml2xmltest.c | 2 + tools/virsh-domain.c | 84 +++++++++++++++++++++++++ 35 files changed, 1151 insertions(+), 2 deletions(-) create mode 100644 tests/genericxml2xmlindata/sev.xml create mode 100644 tests/genericxml2xmloutdata/sev.xml create mode 100644 tests/qemuxml2argvdata/sev.args create mode 100644 tests/qemuxml2argvdata/sev.xml create mode 100644 tests/qemuxml2xmloutdata/sev.xml -- 2.14.3

We install ccache on all guests where it's available, but Fedora is the only one actually using it at the moment, because it enables it automatically.

[libvirt] [PATCH sandbox] Delete the virt-sandbox-service command

by Daniel P. Berrangé

This command attempted to create sandboxed containers for running systemd services that exist on the host. This code has proved very fragile, however, since it needs heuristics to figure out which dirs need to be made private in the container vs shared with the host. Even a relatively simple "httpd.service" sandbox no longer works with current Fedora. Users wanting to sandbox services are better served by using systemd's native container functionality, or using Docker container images. The virt-sandbox-image tool can even run Docker/virt-builder images directly. Signed-off-by: Daniel P.

The -container / virtual machines will be secured by SELinux and resource -separated using cgroups. - -By default, it will use the libvirt LXC driver, with the C<lxc:///> URI. -This is different from libvirt's normal behaviour, which is to probe -for the best URI to use. Thus if using C<virsh> to get a list of containers, -one must specify an explicit URI for it, C<virsh -c lxc:///>.
