[PATCH 0/8] nodedev: add support for ccwgroup based qeth devices
by Boris Fiuczynski 06 Feb '25

06 Feb '25

CCW group devices are devices that use multiple subchannels on the mainframe's channel subsystem. A qeth group device maps to subchannels and their corresponding device numbers and device bus-IDs. The qeth device driver requires three I/O subchannels for each HiperSockets CHPID or OSA-Express CHPID in QDIO mode. One subchannel is for control reads, one for control writes, and the third is for data. The qeth device driver uses the QDIO protocol to communicate with the HiperSockets and OSA-Express adapter. As the node device driver is building a tree relationship between nodes the ccwgroup device is placed besides the subchannel nodes under computer and list the group members within a new ccwgroup capability. A new capability ccwgroup_member is added into capability ccw to represent a device membership to a ccwgroup. Filters are added to find ccwgroups as well as ccwgroup members.

[PATCH] tests: emuxmlconfdata: Update launch-security-sev-snp.xml

Recently, I was part of a discussion where it was suspected that libvirt does not pick up correct FW for SEV-SNP guests. Update our test to demonstrate it does.

[PATCH] nodedev: udev: Hook up virFileWaitForExist to address uevent, race of pci device
by Guoyi Tu 06 Feb '25

06 Feb '25

this commit addresses the same issue that as commit 1af45804 does. the following message is copying from that commit: If we find ourselves in the situation that the 'add' uevent has been fired earlier than the sysfs tree for a device was created, we should use the best-effort approach and give kernel some predetermined amount of time, thus waiting for the attributes to be ready rather than discarding the device from our device list forever. If those don't appear in the given time frame, we need to move on, since libvirt can't wait indefinitely.

Investigating MAC Address Conflict Resolution in libvirt: Log Analysis and Code Location Inquiry
by Xuda Zhang 05 Feb '25

05 Feb '25

Dear Team, I am reaching out regarding an issue I encountered with libvirt and MAC address conflicts. Below is a summary of the situation: 1. Initially, the vNIC's MAC address was different from the target VM's MAC address. 2. After modifying the vNIC's MAC address to match the VM's MAC address, the network was interrupted. 3. After rebooting the VM, the vNIC's MAC address was automatically modified again. I have observed the following kernel logs during this process: Dec 24 16:59:40 zstack-manager kernel: br_enp2s0: port 14(vnic43.0) entered disabled stateDec 24 16:59:40 zstack-manager kernel: device vnic43.0 left promiscuous modeDec 24 16:59:40 zstack-manager kernel: br_enp2s0: port 14(vnic43.0) entered disabled stateDec 24 17:00:11 zstack-manager kernel: br_enp2s0: port 14(vnic43.0) entered blocking stateDec 24 17:00:11 zstack-manager kernel: br_enp2s0: port 14(vnic43.0) entered disabled stateDec 24 17:00:11 zstack-manager kernel: device vnic43.0 entered promiscuous modeDec 24 17:00:11 zstack-manager kernel: br_enp2s0: port 14(vnic43.0) entered blocking stateDec 24 17:00:11 zstack-manager kernel: br_enp2s0: port 14(vnic43.0) entered forwarding state I am looking to understand the underlying code that handles the automatic modification of the vNIC's MAC address after the conflict and how the network interruption occurs. Can you help direct me to the relevant code segment or provide any insights into this behavior? Thank you for your assistance. Best regards,
