Hi,
I've Qemu machine instance with 14 virtio-blk disks and 40 CPU's and
machine type
pc-q35-2.6. I've 2 cases of hypervisor OS, Debian 8 and Debian 9 and following
observations.
1. Host = Debian 8 Machine=pc-q35-2.6 Disks=14 Result=Boots
2. Host = Debian 9 Machine=pc-q35-2.6 Disks=14 Result=Hangs in boot
3. Host = Debian 9 Machine=pc-q35-2.7 or higher Disks=14 Result=Boots
4. Host = Debian 9 Machine=pc-q35-2.6 Disks=11 Result=Boots
We want the scenario 2 to work in our infrastructure but only reducing
the number of disks
as seen in scenario 4 is the only way to get system to boot.
In scenario 2 we observed qemu is showing ~4000% CPU usage. A couple of strace
from the various qemu threads is attached with this mail(kvm_run.txt).
I'm also attaching
domain xml generated by libvirt with this mail.
Below is the ps output of qemu process.
