Public bug reported:
During OFED internal installation the [1] packages removed due to libibverbs1
package dependencies, for example [2].
We see that qemu-system-x86 is depends on libibverbs1 as we see in the apt-case
[2]
Once the qemu-* are deleted, we can't work over virtualization (VM,
SR-IOV,Passthrough, etc..) in hypervisor.
This should impact on user that installed libibverbs1/MLNX_OFED and uses
virtualization.
Could you please assist with knowing the reason of the dependency between
qemu-system-x86 and libibverbs ?
In the older releases we didn't see this issue
