With some more digging, I believe I've found the root of the bug. https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/jammy/tree/debian/rules.d/3-binary- indep.mk
(see also 2-binary-arch.mk for the hv_* daemon binaries, and how they get into their installed location) That makefile is installing the scripts into $(cloudsbin), which looks like it defaults to /usr/sbin, contrary to the path embedded in the hv_kvp_daemon binary and the corresponding Makefile over in jammy/tools/hv. I think hv_* should live in /usr/libexec/hypervkvpd, and only lsvmbus should live in /usr/sbin (as it has some diagnostic utility). I think rules.d/* needs to changed to eliminate the path mismatch involved in this bug. If consensus says these things should live in /usr/sbin, then I'm ok with that too (and the path embedded in the hv_kvp_daemon binary needs to be changed). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-azure in Ubuntu. https://bugs.launchpad.net/bugs/1766857 Title: [Hyper-V] KVP daemon fails to start Status in linux package in Ubuntu: Confirmed Status in linux-azure package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Status in linux-azure source package in Bionic: Confirmed Status in linux source package in Cosmic: Confirmed Status in linux-azure source package in Cosmic: Confirmed Bug description: While testing Bionic daily build with kernel 4.15.0-20-generic we saw that there are 2 issues with the KVP daemon: 1. KVP daemon crash after boot. Opened a different bug for this: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1779640 2. After the KVP daemon is being started the following messages appear: Apr 25 04:45:25 bionicDaily hv_kvp_daemon[1895]: sh: 1: /usr/libexec/hypervkvpd/hv_get_dns_info: not found Apr 25 04:45:25 bionicDaily hv_kvp_daemon[1895]: sh: 1: /usr/libexec/hypervkvpd/hv_get_dhcp_info: not found The above binaries are present on the system, but the their actual path is /usr/sbin/hv_get_dns_info and /usr/sbin/hv_get_dhcp_info. Either the hv_get_dhcp_info and hv_get_dns_info binaries should be placed in the location where the daemon is looking for (/usr/libexec/hypervkvpd/), or the daemon should be set to search for the binaries in the /usr/sbin directory.
