similar to: systemd-udevd not applying ATTR to block device at boot

The mtx binary requires my tape library to be assigned a sg# driver, but the kernel periodically renumbers the sg devices. Normally, we would write a udev rule to manually assign a persistent name, but it looks like things have changed as I can't seem to get a match on CEntOS7. I'd appreciate any feedback or pointers to help me get my rule working. My two attempts are below. cat

virtio-mem: add memory via add_memory_driver_managed() On Thu, Jun 11, 2020 at 11:35:18AM +0200, David Hildenbrand wrote: > Virtio-mem managed memory is always detected and added by the virtio-mem > driver, never using something like the firmware-provided memory map. > This is the case after an ordinary system reboot, and has to be guaranteed > after kexec.

Virtio-mem managed memory is always detected and added by the virtio-mem driver, never using something like the firmware-provided memory map. This is the case after an ordinary system reboot, and has to be guaranteed after kexec. Especially, virtio-mem added memory resources can contain inaccessible parts ("unblocked memory blocks"), blindly forwarding them to a kexec kernel is

Hi, I just tried to hot-plug a virtio disk to a CentOS 5.10 guest that runs on a CentOS 6.5 host. The Problem is that while the device shows up under /sys/ the corresponding device node does not: /sys/devices/virtio-pci/virtio0: bus device driver modalias net:eth0 power status subsystem uevent vendor /sys/devices/virtio-pci/virtio1: block:vda bus device driver modalias power serial

Implement a virtio-iommu device and translate DMA traffic from vfio and virtio devices. Virtio needed some rework to support scatter-gather accesses to vring and buffers at page granularity. Patch 3 implements the actual virtio-iommu device. Adding --viommu on the command-line now inserts a virtual IOMMU in front of all virtio and vfio devices: $ lkvm run -k Image --console virtio -p

I was hoping that we could use QMP (now semi-stable since qemu 0.14) to hot plug disks. Unfortunately this is not yet possible. There is no drive_add QMP command which would be necessary for adding drives. We (Red Hat) hacked in a drive_add command into RHEL 6 (only for use by libvirt). This doesn't help us with upstream or Fedora. We could still use the human monitor, but obviously this

This is useful for debugging (but we can't print it unconditionally since we cannot run grep etc yet). It also allows us to identify when udevd is invoked so we can time it for boot analysis. --- appliance/init | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/appliance/init b/appliance/init index f6fe9b9..657943c 100755 --- a/appliance/init +++ b/appliance/init @@

I suppose it would help if I posted relevant version info (sorry about that...)
