andrijapanicsb commented on issue #3089: VMs with invalid IDE configuration when using Solidfire as primary storage URL: https://github.com/apache/cloudstack/issues/3089#issuecomment-454940213 @DennisKonrad @svenvogel I might sound silly - beside this being a potential bug, why would you want to ever use "windows server 2016" as OS type, since only "Windows PV" is the one offering VirtIO hardware/drivers ? Both disk and NIC are extremely slow - a.k.a. almost unusable ? Using any Windows Server XXX version as the OS Type- should NOT give any virtio drivers/hardware to VM - this is used for compatibility purposes, to be able to run UNMODIFIED Windows Server OS. On the other hand - did you observe this on 4.11.2 version ? I'm just testing as we speak (4.11.2) - and have successfully booted new VM from Centos5 template (which was marked as OS Type "Windows Server 2016 x64" - so binaries are not relevant here) - it started the VM just fine, as shown below - 2 disk with IDE, and another IDE cdrom I'm about to test spinning same setup as yours from ISO (with only 1 additional IDE drive) - and will report here... (again in 4.11.2) BTW, if you deploy a VM with single volume - and later attach (hotplug multiple volumes - do they get VirtIO type or not ?) - if so, this is a known bug actually -after stopping the VM and starting it again I assume they will all get back to IDE drives (I observed this on NFS/CEPH back in 4.8 release) Please try using Windows PV - as this one is meant to be used to provide Virtio (SCSI and NIC) to OS. Thx. ``` <domain type='kvm' id='4'> <name>i-2-9-VM</name> <uuid>888af124-031a-48f3-b8c6-e9df5ff295d7</uuid> <description>Windows Server 2016 (64-bit)</description> <memory unit='KiB'>33554432</memory> <currentMemory unit='KiB'>33554432</currentMemory> <vcpu placement='static'>4</vcpu> <cputune> <shares>8000</shares> <period>10000</period> <quota>5900</quota> </cputune> <resource> <partition>/machine</partition> </resource> <sysinfo type='smbios'> <system> <entry name='manufacturer'>Apache Software Foundation</entry> <entry name='product'>CloudStack KVM Hypervisor</entry> <entry name='uuid'>888af124-031a-48f3-b8c6-e9df5ff295d7</entry> </system> </sysinfo> <os> <type arch='x86_64' machine='pc-i440fx-2.5'>hvm</type> <boot dev='cdrom'/> <boot dev='hd'/> <smbios mode='sysinfo'/> </os> <features> <acpi/> <apic/> <pae/> </features> <cpu mode='custom' match='exact'> <model fallback='allow'>SandyBridge</model> <topology sockets='1' cores='4' threads='1'/> </cpu> <clock offset='localtime'> <timer name='rtc' tickpolicy='catchup'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/bin/kvm-spice</emulator> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source dev='/dev/disk/by-path/ip-10.XX.YY.32:3260-iscsi-iqn.2010-01.com.solidfire:hdqi.root-9.8136-lun-0'/> <backingStore/> <target dev='hda' bus='ide'/> <serial>e951de35b9ab461f8b4c</serial> <alias name='ide0-0-0'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source dev='/dev/disk/by-path/ip-10.XX.YYY.32:3260-iscsi-iqn.2010-01.com.solidfire:hdqi.data-9.8137-lun-0'/> <backingStore/> <target dev='hdb' bus='ide'/> <serial>ef89722f275240458db8</serial> <alias name='ide0-0-1'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <backingStore/> <target dev='hdc' bus='ide'/> <readonly/> <alias name='ide0-1-0'/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> <controller type='usb' index='0'> <alias name='usb'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/> </controller> <controller type='pci' index='0' model='pci-root'> <alias name='pci.0'/> </controller> <controller type='ide' index='0'> <alias name='ide'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <alias name='virtio-serial0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> ```
