Description zhoujunqin 2022-01-05 09:02:30 UTC 
Description of problem:
[virt-install] Should add 'ioapic' to the support of "virt-install --features=?"

Version-Release number of selected component (if applicable):
virt-install-3.2.0-2.el8.noarch
libvirt-7.8.0-1.module+el8.6.0+12982+5e169f40.x86_64
qemu-kvm-6.1.0-5.module+el8.6.0+13430+8fdd5f85.x86_64


How reproducible:
100%

Steps to Reproduce:
1. Install a VM with 260 vcpus via virt-install command.
# virt-install --machine=q35 --noreboot --name=rhel86 --memory=4096 --vcpus=260 --graphics type=vnc  --location http://download.eng.pek2.redhat.com/released/rhel-6-7-8/rhel-8/RHEL-8/8.4.0/BaseOS/x86_64/os/ --iommu model=intel,driver.intremap=on,driver.eim=on,driver.caching_mode=on --features acpi=on

ERROR    unsupported configuration: IOMMU interrupt remapping requires split I/O APIC (ioapic driver='qemu')
Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
  virsh --connect qemu:///system start rhel86
otherwise, please restart your installation.

Test result - Failed to install the VM.

2. Check the elements supported by --features.
# virt-install --features=?
--features options:
  clearxml
  acpi
  apic
  apic.eoi
  gic.version
  hap
  hyperv.relaxed.state
  hyperv.reset.state
  hyperv.spinlocks.retries
  hyperv.spinlocks.state
  hyperv.synic.state
  hyperv.vapic.state
  kvm.hidden.state
  kvm.hint-dedicated.state
  pae
  pmu.state
  privnet
  pvspinlock.state
  smm.state
  viridian
  vmcoreinfo.state
  vmport.state


Actual results:
As for the description.

Expected results:
Add the "ioapic" elements to the "--features".

Additional info:
Libvirt has already supported this feature.

Comment 8 Hongzhou Liu 2022-01-25 13:04:47 UTC 
Pre-verification with 

Packages:
virt-install-3.2.0-3.el8.noarch
qemu-kvm-6.2.0-4.module+el8.6.0+13930+1ccead3d.x86_64
libvirt-8.0.0-1.module+el8.6.0+13896+a8fa8f67.x86_64

Step 1. 
Check the sub-options for 
#virt-install --feature=?
--features options:
  clearxml
  acpi
  apic
  apic.eoi
  gic.version
  hap
  hyperv.relaxed.state
  hyperv.reset.state
  hyperv.spinlocks.retries
  hyperv.spinlocks.state
  hyperv.synic.state
  hyperv.vapic.state
  ioapic.driver
  kvm.hidden.state
  kvm.hint-dedicated.state
  pae
  pmu.state
  privnet
  pvspinlock.state
  smm.state
  viridian
  vmcoreinfo.state
  vmport.state
Result: ioapic.driver has been added.

Step 2.
Run the command blow to install a vm
#virt-install 
--machine=q35 \ 
--noreboot \
--name=rhel86 \
--memory=4096 \
--vcpus=200 \
--graphics type=vnc \  
--location http://download.eng.pek2.redhat.com/released/rhel-6-7-8/rhel-8/RHEL-8/8.4.0/BaseOS/x86_64/os/ \
--iommu model=intel,driver.intremap=on,driver.eim=on,driver.caching_mode=on \ --features  apic=on,ioapic.driver=qemu \
Result: vm can be installed as expected

Step 3.
Check the xml configuration:
…
<features>
    <acpi/>
    <apic/>
    <ioapic driver='qemu'/>
  </features>
…
 <iommu model='intel'>
      <driver intremap='on' caching_mode='on' eim='on'/>
    </iommu>
	…
	Result: xml config generated correctly, So I change verified status to tested.
