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 v1: * better document this behavior * show better hints in the UI * improve test case qemu-server: Stefan Hanreich (1): net: pass host_mtu parameter when mtu is unset in netdev config PVE/QemuServer.pm | 30 ++++++++++++++++-------------- test/cfg2cmd/netdev_vxlan.conf | 7 +++++++ test/cfg2cmd/netdev_vxlan.conf.cmd | 28 ++++++++++++++++++++++++++++ test/run_config2command_tests.pl | 6 ++++++ 4 files changed, 57 insertions(+), 14 deletions(-) create mode 100644 test/cfg2cmd/netdev_vxlan.conf create mode 100644 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: 6 files changed, 61 insertions(+), 19 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
