[network.pm, qemuserver.pm] Subject: [pve-devel] [PATCH docs/manager/qemu-server v3 0/3] Make VirtIO network devices inherit MTU from bridge by default X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Reply-To: Proxmox VE development discussion Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: pve-devel-bounces@lists.proxmox.com Sender: "pve-devel" The current default behavior for VirtIO network devices is to default to 1500 MTU, unless otherwise specified. This is inconvenient in cases where the MTU is not the default value (e.g. for VXLAN VNets or bridges with jumbo frames). Containers already inherit the MTU of the bridge, if not set, so change the behavior of VMs to be more in line with containers. This also makes using non-standard MTUs more convenient and less error-prone since users do not have to remember setting the MTU everytime they configure a network device on such a brige. Changes from v2: * rebase on top of re-formatted code * fix tests with new qemu version Changes from v1: * better document this behavior * show better hints in the UI * improve test case qemu-server: Stefan Hanreich (1): net: automatically set host_mtu to bridge mtu for virtio netdevs src/PVE/QemuServer.pm | 30 ++++++++++++++------------ src/PVE/QemuServer/Network.pm | 3 ++- src/test/cfg2cmd/netdev_vxlan.conf | 7 ++++++ src/test/cfg2cmd/netdev_vxlan.conf.cmd | 28 ++++++++++++++++++++++++ src/test/run_config2command_tests.pl | 6 ++++++ 5 files changed, 59 insertions(+), 15 deletions(-) create mode 100644 src/test/cfg2cmd/netdev_vxlan.conf create mode 100644 src/test/cfg2cmd/netdev_vxlan.conf.cmd pve-manager: Stefan Hanreich (1): qemu: network: adjust MTU emptyText to match new default behavior www/manager6/qemu/NetworkEdit.js | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) pve-docs: Stefan Hanreich (1): qm: document new default behavior for mtu setting qm.adoc | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) Summary over all repositories: 7 files changed, 63 insertions(+), 20 deletions(-) -- Generated by git-murpp 0.8.0 _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
