Hi everyone!
It's the first time I send a message to this list, I hope it's not the last :)
So my issue is that when booting a disk image generated with virt-builder [1]
it takes more than 5 minutes, waiting in the boot screen that says:
"
Booting from disk...
press any key to continue.
"
The press any key message shows up to 5 times. The issue is that it stays in
that screen for more than 5 min.
If I attach a serial pty device, then it takes ~5 seconds to go through that
screen (same messages, just show faster).
I don't want to have to create a pty device each time I want to spin up a vm
(if there's a way to tell libvirt to do that for me that would be ok too).
Is there any workaround I can do to avoid having to create a pty and still get
fast boot?
The xml of the slow vm:
<domain type='kvm'>
<name>fedora23</name>
<memory unit='MiB'>2048</memory>
<vcpu>1</vcpu>
<cpu mode='host-passthrough'>
<topology sockets='1' cores='1' threads='1'/>
</cpu>
<os>
<type arch='x86_64' machine='pc'>hvm</type>
<boot dev='hd'/>
<bootmenu enable='yes' timeout='3000'/>
</os>
<features>
<acpi/>
<apic/>
<pae/>
</features>
<devices>
<emulator>/usr/libexec/qemu-kvm</emulator>
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/tmp/fedora-23.qcow2'/>
<target dev='sda' bus='virtio'/>
</disk>
<graphics type='vnc' port='-1' autoport='yes'
listen='0.0.0.0' keymap='en-us'/>
<channel type='unix'>
<source mode='bind'/>
<target type='virtio' name='org.qemu.guest_agent.0'/>
</channel>
</devices>
</domain>
The same with this device boots fast:
<serial type='pty'>
<source path='/dev/pts/12'/>
<target port='0'/>
<alias name='serial0'/>
</serial>
