[PATCH] [Kimchi 0/5] VEPA network support

by dhbarboza82＠gmail.com

From: Daniel Henrique Barboza <dhbarboza82(a)gmail.com> This patch set implements the VEPA network support for Kimchi in the backend and the frontend. VEPA networks are somewhat similar to bridge networks that tunnels traffic between VMs by using an external VEPA-enabled switch that will process and forward the frames faster than the host CPU/OS can do. The UI support is similar to what we already have for the bridge network. ATM the UI doesn't support multiple physical devices being assigned to a single VEPA network but the backend does. This can be enhanced in the future with an UI patch. The idea was to have some UI support to get the feature alive ASAP. To create a VEPA network the process is similar to the bridge network with an extra parameter called 'vepa_devs', an array of physical devices. Let me show an example of use: 1- creating the VEPA network (can be done via the UI): [danielhb@arthas kimchi]$ curl -k -u root -H "Content-Type: application/json" -H "Accept: application/json" -X POST 'https://localhost:8001/plugins/kimchi/networks' -d'{"name":"vepa_net", "connection":"vepa", "vepa_devs":["enp0s25"]}' Enter host password for user 'root': { "in_use":false, "persistent":true, "interface":"", "vms":[], "subnet":"", "vepa_devs":[ "enp0s25" ], "name":"vepa_net", "state":"inactive", "connection":"vepa", "autostart":true, "dhcp":{ "start":"", "end":"" } }[danielhb@arthas kimchi]$ - this is the generated network XML in libvirt: [danielhb@arthas kimchi]$ sudo virsh net-dumpxml vepa_net <network> <name>vepa_net</name> <uuid>96da7b58-d655-4fa2-b0f6-d9a026cbf95a</uuid> <forward dev='enp0s25' mode='vepa'> <interface dev='enp0s25'/> </forward> </network> [danielhb@arthas kimchi]$ 2 - In Kimchi UI: - activate the network - create (or edit) a template and add this network to an interface - create a VM using that template. This is the result interface XML of the VM: <interface type='network'> <mac address='52:54:00:77:31:30'/> <source network='vepa_net'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> And this is the backend call showing the status of the 'vepa_net' network after these steps: [danielhb@arthas kimchi]$ curl -k -u root -H "Content-Type: application/json" -H "Accept: application/json" -X GET 'https://localhost:8001/plugins/kimchi/networks/vepa_net' Enter host password for user 'root': { "in_use":true, "persistent":true, "interface":"", "vms":[ "vepa-vm" ], "subnet":"", "vepa_devs":[ "enp0s25" ], "name":"vepa_net", "state":"active", "connection":"vepa", "autostart":true, "dhcp":{ "start":"", "end":"" } }[danielhb@arthas kimchi]$ Daniel Henrique Barboza (5): VEPA network support: API and i18n changes VEPA network support: xmlutils changes VEPA network support: changes in networks control and model VEPA network support: additional backend unit tests VEPA network support: UI changes API.json | 2 +- control/networks.py | 5 +++-- docs/API.md | 5 +++++ i18n.py | 5 +++-- model/networks.py | 14 ++++++++++-- tests/test_networkxml.py | 42 +++++++++++++++++++++++++++++++++++- ui/js/src/kimchi.network.js | 9 ++++++-- ui/js/src/kimchi.network_add_main.js | 19 ++++++++++------ ui/pages/network-add.html.tmpl | 5 +++-- xmlutils/network.py | 25 +++++++++++++++++++-- 10 files changed, 111 insertions(+), 20 deletions(-) -- 2.5.0

[PATCH] [Kimchi 0/6] Web serial console

by Jose Ricardo Ziviani

This is the initial version of a web serial console for kimchi/libvirt VMs. When a VM is turned on, a new action is displayed named "Connect Serial", this will open a new tab with an interface like the existing novnc. That interface opens a websocket to kimchi webserver (nginx), then it is redirected to websockify. Websockify will proxy that connection to a local unix socket server to finally communicate with the guest console. I chose to create one server per guest because that's the way websockify was designed (it was born inside novnc), so I could reuse the token security plugin implemented in websockify. In order to avoid wasting resources I decided to user unix socket, a local/lightweight/reliable socket if compared with internet sockets, this uses files instead of ports to accept connections. When a connection is established no one else can get that console (I'm not multiplexing it but it's possible in future). The serial console will be available again if the current user does one of: - type ctrl+q - close the tab - 2 min. timeout Thanks Jose Ricardo Ziviani (6): Rename vnc.py to websocket.py Implement the web serial console server Implement the backend to support web serial console Implement the web serial console front-end Implement the Kimchi front-end for the web serial console Add test case for the socket server control/vms.py | 3 +- i18n.py | 4 +- kimchi.conf | 6 + model/vms.py | 43 +- root.py | 8 +- serial_console.py | 291 ++ tests/test_model.py | 30 +- ui/js/src/kimchi.api.js | 25 + ui/js/src/kimchi.guest_main.js | 16 +- ui/pages/guest.html.tmpl | 5 +- ui/serial/images/favicon.ico | Bin 0 -> 15086 bytes ui/serial/images/logo-white.png | Bin 0 -> 7583 bytes ui/serial/serial.html | 80 + ui/serial/term.js | 5973 +++++++++++++++++++++++++++++++++++++++ vnc.py | 92 - websocket.py | 122 + 16 files changed, 6587 insertions(+), 111 deletions(-) create mode 100644 serial_console.py create mode 100644 ui/serial/images/favicon.ico create mode 100644 ui/serial/images/logo-white.png create mode 100644 ui/serial/serial.html create mode 100644 ui/serial/term.js delete mode 100644 vnc.py create mode 100644 websocket.py -- 1.9.1

[PATCH] [Kimchi] [RFC] Create new volume and attach to VM

by Socorro Stoppler

This is the initial checkin for creating a new volume and attaching to VM when editing a guest. Not sure of all the supported cases, but tried default pool and qcow2 format per the example provided in the back-end patch and it was successful. Known issue - which currently exists in the code already in master - code is broken when VM is running. This patch does not address that. It will get addressed separately.
