[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-users] Xen 4.7 ram allocation bug ?
I have been trying for some time now to upgrade from Xen 4.6.* to 4.7.
Trying several different dom0 kernel versions, and jiggling the xl.cfg
files. All to no avail.
I am unable to launch most of my guests under 4.7, though they run fine
under 4.6 (except for some usb/pci-pass-though -related issues) . As
seen from the device-model log below, qemu claims it is unable to
allocate ram: "qemu: hardware error: xen: failed to populate ram at
280050000", but I have plenty ram available, and this same VM (and many
more) launch fine under 4.6.*
I admit I am a rank amateur at this, so my config is probably pretty
weird, possibly leading to a set-up that nobody knowledgeable would run.
If somebody can give me a hint on how to work around this issue I'll
happily test patches and provide logs.
Example VM which does not start under 4.7. :
------xl.cfg for media.hvm (i pass pci-pass-through for usb-card on
command-line. Works OK)name = "media.hvm"
builder = "hvm"
xen_platform_pci = '1'
pvh=1
memory = 7168
mmio_hole=3072
vcpus = 6
cap=600
cpus_soft="node:0"
cpu_weight=6144
device_model_version="qemu-xen"
serial = 'pty'
disk = [ 'vdev=xvda, format=raw, target=/dev/system/media-backend'
,'vdev=xvdb, format=raw, target=/dev/system/media-backend-swap'
,'vdev=xvdd, format=raw, target=/dev/system/apub'
,'vdev=xvde, format=raw, target=/dev/system/apub1'
,'vdev=xvdf, format=raw, target=/dev/system/apub2'
,'vdev=xvdg, format=raw, target=/dev/system/apub3'
,'vdev=xvdh, format=raw, target=/dev/system/apub4'
,'vdev=xvdi, format=raw, target=/dev/system/apub5'
,'vdev=xvdj, format=raw, target=/dev/system/apub6'
,'vdev=xvdk, format=raw, target=/dev/system/apub7' ]
kernel = "/etc/xen/media-boot/vmlinuz-4.1.12-gentoo"
extra = "root=/dev/xvda intel_iommu=on console=ttyS0 console=vga
init=/usr/lib/systemd/systemd elevator=deadline xen_blkfront.max=128"
vif = ['mac=02:16:3e:00:00:07,bridge=br0']
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
boot = 'd'
acpi = '1'
sdl = '0'
vnc = '1'

This results in the following:
