[PATCH 0/5] qemu: respond to NETDEV_VHOST_USER_DISCONNECTED event by starting a new passt process
by Laine Stump 11 Apr '25

11 Apr '25

This brings behavior of passt+vhostuser in line with trad-passt - if the passt process is somehow terminated, libvirt will start a new passt process that qemu will connect to. You'll notice no change in behavior if your QEMU binary doesn't have the patches that add NETDEV_VHOST_USER_DISCONNECTED to qemu, but also nothing extra will fail. The requisite QEMU patches are upstream in commit 02fd9f8aeeb1 ("net: vhost-user: add QAPI events to report connection state"), which will be in upstream qemu-10.0.0. Resolves: https://issues.redhat.com/browse/RHEL-80169 Laine Stump (5): qemu: remove nonsensical sanity check in processNetdevStreamDisconnectedEvent() qemu: make processNetDevStreamDisconnectedEvent() reusable qemu: respond to NETDEV_VHOST_USER_DISCONNECTED event qemu: put vhost-user code that's special for passt in a helper function qemu: make passt+vhostuser reconnect behave identically to passt+user src/qemu/qemu_domain.c | 1 + src/qemu/qemu_domain.h | 1 + src/qemu/qemu_driver.c | 55 ++++++++++++------- src/qemu/qemu_hotplug.c | 7 +-- src/qemu/qemu_monitor.c | 11 ++++ src/qemu/qemu_monitor.h | 6 ++ src/qemu/qemu_monitor_json.c | 16 ++++++ src/qemu/qemu_passt.c | 25 +++++++++ src/qemu/qemu_passt.h | 3 + src/qemu/qemu_process.c | 27 ++++++--- .../net-vhostuser-passt.x86_64-latest.args | 6 +- ...rder-domain-subelements.x86_64-latest.args | 2 +- 12 files changed, 122 insertions(+), 38 deletions(-) -- 2.49.0

[PATCH] esx: Accept empty "path" URI component same way as "/"
by Peter Krempa 09 Apr '25

09 Apr '25

From: Peter Krempa <pkrempa(a)redhat.com> When connecting to "esx://" URI there's code which prints a warning that the path is not "empty". The check validates that "uri->path" is "/". In case when the user uses URI such as: esx://hostname the warning is printed as well. Since there is no effective difference betweeen the two allow empty strings as well.

[PATCH] bhyve: support interface type 'network'
by Roman Bogorodskiy 09 Apr '25

09 Apr '25

Add support for interface type 'network'. While bridge remains the only supported options for networks in bhyve, supporting interface type 'network' allows easier configuration and makes domain XMLs more compatible with the other drivers. While here, update the error message for the unsupported interface type to print the requested network type string instead of an integer to make it more user-friendly.
